Question

can anyone explain to me what are the differences between iso-propyl and sec-propyl. is sec-propyl do exist? keep on confusing this thing.

Answer 1

we don't have iso-propyl but sec-propyl exist

Answer 2

Isopropyl means three carbons, one carbon linked to two similar carbon groups.
For eg, isopropyl chloride is CH3-CH(Cl)-CH3, and here the similar groups are methyl groups.

Sec-propyl means 3 carbons, one of them being a secondary carbon.
For eg, sec-propyl chloride. But in this case, both sec-propyl and isopropyl are the same, because of the methyl groups.
