Answer 1

Answer: Please see attachments below

Explanation: Please see the attachments below

Then for (f), The name given is 2,3-diethyl-5-isopropylheptane. This means there is a seven carbon chain with two ethyl groups on positions two and three and an isopropyl group on position five.

See the structure on the attachment for question (e).

The naming of the compound is wrong because, the longest chain carrying the highest number of substituents is not considered as the parent chain. The correct numbering of the parent chain is shown in the structure. The correct name of the company is:

4-ethyl-6-isopropyl-3-methyloctane
