Question

How many carbons are in simplest alkyne having two side chains?

Answer 1

It may be CH≡C-C(CH3)3 or (CH3)2CHC≡C-CH (CH3)2

Answer 2

Answer:- Six carbons and the compound is 3,3-Dimethyl-1-butyne.

Explanations:- It asks about the simplest formula for the alkyne having two side chains. So, No side chain is possible for the carbons bonded via a triple bond. So, there has to be minimum 4 carbons parent chain and then the third carbon from the triple bond side has to have two methyl groups.

The compound is 3,3-Dimethyl-1-butyne and it has total six carbons. The structure is shown in the attachment.
