Question

1. for the following structure:

a) identify the parent chain. how many carbons does it have?
b) what name is the name of the parent?
c) what are the names of the substituents, as #-name (ex: 3 - methyl, 2 - butyl, etc.)?

Explanation:

Step1: Find the longest chain

The longest continuous carbon - carbon chain is the parent chain. By inspection, the longest chain has 10 carbons.

Step2: Name the parent

For an alkane with 10 carbons, the parent name is decane.

Step3: Identify and name substituents

There are two methyl groups. One is on the 3rd carbon and the other is on the 6th carbon. So the substituents are 3 - methyl and 6 - methyl.

Answer:

a) The parent chain has 10 carbons.
b) Decane
c) 3 - methyl, 6 - methyl
