Question

How many minimum carbon atoms are present in an alkene having 2 side chain?

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.
