Question

Difference between:- 1. iso alkyl and sec alkyl. 2. Neo alkyl and Tert alkyl


Also please correct me if the structure drawn by me is wrong.​

Answer 1

Explanation:

Structures are accurate!

Secondary group is attachment site for the group on the parent chain is $2^{0}$ carbon.

Iso group has a standard structure

$CH_{3} - C'H-CH_{3}$ is an iso group

C' is the site where it is attached to the main parent chain.

Similarly Tertiary group is attachment site for the group on the parent chain is $3^{0}$ carbon.

Neo group has attachment on

$(CH_3)_{3} -C-C'H_{2}$

C' is the site where it is attached to the main parent chain.

Refer attachment for clarification.

FYI: each point in the zig zag line diagram is carbon and end points are methyl groups.

Kudos!
