Answer 1

Ch3

The ene functional group is preferred over yne-group if both are present at same distance from their respective terminal carbons. Here from right side of the chain yne-group is present at 2nd carbon and ene-group is also present at 2nd carbon from left side of the chain. Hence, the numbering is done from the left side.

Hence, the IUPAC name of the compound is

Octa−2,4−diene−6−yne
