Q.39. - Organic Chemistry

Question

Question: Give the structure and IUPAC name for each of the nine isomers having molecular formula ${\mathit{C}}_{\mathbf{9}}{\mathit{H}}_{\mathbf{20}}$ that contains seven carbons in the longest chain and two methyl groups as substituents.

Step-by-Step Solution

Answer

Answer

Step 1: Isomers

Isomers are shown by the same molecular formula but different structural representations.

Step 2: IUPAC naming

The IUPAC naming of the compound follows the longest chain of carbons. The counting is started from the side where the substituents are the closest. Moreover, the alphabetical order is followed for the naming.

Step 3: Explanation

The nine isomers of $C_9{H}_{20}$  with seven carbon chains is shown as follows:
