Question

Question: Draw all possible skeletons for a 7-C compound with

(a) A 6-C chain and 1 double bond

(b) A 5-C chain and 1 double bond

(c) A 5-C ring and no double bonds

Step-by-Step Solution

Answer

The possible skeleton for the 7-C compound are:

(a) A 6-C chain and one double bond have 11 possible structures:

(b) A 5-C chain and one double bond also represent 11 possible structures:

                         

(c) A 5-C ring and no double bonds represent four possible structures.

Step 1: Formulas for depicting organic molecules

Different formulas are used to easily represent the structure of organic compounds, such as expanded formulas, carbon-skeleton formulas, and condensed formulas. However, the ball and stick model is used to represent the original shapes of the molecules. These formulas also have importance to organic molecules’ structural representation.

In the expanded formula, the structure represents all the atoms and bond linkages.

The structure includes all the atoms in the condensed formula, but the linkage of only the carbon atom is shown.

The Skeleton formula only shows linkages of the carbon atom.

Step 2: Draw all the possible structures for a 7C compound

(a) A 6-C chain and one double bond have 11 possible structures:

(b) A 5-C chain and one double bond also represent 11 possible structures:

(c) A 5-C ring and no double bonds represent four possible structures.
