A structural formula uses lines to show the bonds between the atoms. A condensed structural formula omits most or all the bonds. A structural formula tells us which atoms are in a molecule. It also shows us how they connect to each other.

Structural Formula

There are different types of structural formula. The least complicated structural formula tells us which atoms connect to which. A condensed structural formula is a system of writing organic structures so we can type them in a line of text. A condensed structural formula uses parentheses to show that polyatomic groups within a formula are attached to the nearest non-hydrogen atom on the left. It also uses parentheses to show that polyatomic groups at the beginning of a formula are attached to the atom on the right.

What is the difference between a condensed structural formula and a structural formula? Ernest Z. Dec 23, Explanation: Structural Formula A structural formula tells us which atoms are in a molecule. Below are the structural formulas of ethane, propane and ethanol. Condensed Structural Formula A condensed structural formula is a system of writing organic structures so we can type them in a line of text. It shows all atoms, but omits the vertical bonds and most or all the horizontal ones.

You can reuse this answer Creative Commons License.We use several kinds of formulas to describe organic compounds. A molecular formula shows only the kinds and numbers of atoms in a molecule. A structural formula shows all the carbon and hydrogen atoms and the bonds attaching them. Thus, structural formulas identify the specific isomers by showing the order of attachment of the various atoms.

Chemists often use condensed structural formulas to alleviate these problems. The condensed formulas show hydrogen atoms right next to the carbon atoms to which they are attached, as illustrated for butane:. Even more abbreviated is a line-angle formula, also called a skeletal structurein which carbon atoms are implied at the corners and ends of lines, and each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds.

All other types of atoms are shown and hydrogens bonded to atoms other than carbon are shown. Parentheses in condensed structural formulas indicate that the enclosed grouping of atoms is attached to the adjacent carbon atom. Below is an example of a more complicated molecule.

On the left is shown the complete Lewis structure, showing all atoms and valence electrons. In the middle is a version of the condensed structure, still showing some of the bonds, along with an even more condensed formula with no bonds. Finally, on the right is the line-angle skeletal structure; notice that the bonds are shown, but not the carbons and not the hydrogens bonded to carbon. The following are suggested steps for drawing a line-angle structure also known as a skeletal structure.

Draw the Lewis structure of the molecule below, showing all atoms and all valence electrons bonds and lone pairs. Skills to Develop Write condensed structural formulas for alkanes given complete structural formulas. Draw line-angle formulas given structural formulas.

Key Takeaways Condensed chemical formulas show the hydrogen atoms or other atoms or groups right next to the carbon atoms to which they are attached. Line-angle formulas imply a carbon atom at the corners and ends of lines. Each carbon atom is understood to be attached to enough hydrogen atoms to give each carbon atom four bonds. Exercises 1. Draw the Line-Angle structure for the molecule below. Answers A.Methoxypropaneor methyl propyl etheris an ether once used as a general anaesthetic.

Marketed under the trade names Metopryl and Neothylmethoxypropane was used as an alternative to diethyl ether because of its greater potency. Its use as an anaesthetic has since been supplanted by modern halogenated ethers which are much less flammable.

Download as PDF Printable version.When drawing the structure of a neutral organic compound, you will find it helpful to remember that. It is necessary to draw structural formulas for organic compounds because in most cases a molecular formula does not uniquely represent a single compound.

Different compounds having the same molecular formula are called isomersand the prevalence of organic isomers reflects the extraordinary versatility of carbon in forming strong bonds to itself and to other elements. When the group of atoms that make up the molecules of different isomers are bonded together in fundamentally different ways, we refer to such compounds as constitutional isomers. There are seven constitutional isomers of C 4 H 10 O, and structural formulas for these are drawn in the following table.

These formulas represent all known and possible C 4 H 10 O compounds, and display a common structural feature. There are no double or triple bonds and no rings in any of these structures. Simplification of structural formulas may be achieved without any loss of the information they convey.

In condensed structural formulas the bonds to each carbon are omitted, but each distinct structural unit group is written with subscript numbers designating multiple substituents, including the hydrogens. Shorthand line formulas omit the symbols for carbon and hydrogen entirely. Each straight line segment represents a bond, the ends and intersections of the lines are carbon atoms, and the correct number of hydrogens is calculated from the tetravalency of carbon.

Non-bonding valence shell electrons are omitted in these formulas. Developing the ability to visualize a three-dimensional structure from two-dimensional formulas requires practice, and in most cases the aid of molecular models. As noted earlier, many kinds of model kits are available to students and professional chemists, and the beginning student is encouraged to obtain one.

A structural formula displays the atoms of the molecule in the order they are bonded. It also depicts how the atoms are bonded to one another, for example single, double, and triple covalent bond. Covalent bonds are shown using lines. The number of dashes indicate whether the bond is a single, double, or triple covalent bond. Structural formulas are helpful because they explain the properties and structure of the compound which empirical and molecular formulas cannot always represent.

Condensed structural formulas show the order of atoms like a structural formula but are written in a single line to save space and make it more convenient and faster to write out. Condensed structural formulas are also helpful when showing that a group of atoms is connected to a single atom in a compound.

When this happens, parenthesis are used around the group of atoms to show they are together. Because organic compounds can be complex at times, line-angle formulas are used to write carbon and hydrogen atoms more efficiently by replacing the letters with lines.

A carbon atom is present wherever a line intersects another line. All other atoms that are connected to carbon atoms are written out.That is a molecular formula. I can't off the top of my head think of any compound with that molecular formula, though. It's not methoxyethane or a propanol, because it's got one too few hydrogen atoms.

It's not propanone or cyclopropanol or oxetane or a propenol, because it's got one too many hydrogen atoms. The formula which only shows the number of carbon and hydrogen atoms present in the molecule without representing the bond present in the molecule is called Condensed structural formula. It only gives a relation between atoms but does not show carbon carbon bond in organic compounds.

The condensed structural formula for hexane is C6H Is the molecular formula which indicates the main carbon-carbon bonds, or other type of atoms except the hydrogen-carbon bonds Example:. Methyl salicylate oil of wintergreen or wintergreen oil is an organic ester naturally produced by many species.

Its molecular formula is C8H8O3. The microwave does not have a molecular formula. It is the foods that we heat in a microwave that has the molecular formula. Molecular formula is the actual representation of the constitution of the substancewhile Empirical formula is the simplest representation of the molecular formula. The condensed structural formula for the compound 1-Octanol is C8H18O. By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
