​

Answer 1

Explanation:

I think here is no allylic and vinylic halide present because as per the defination both these require carbon- carbon double bond and here is triple bond and its definately not a benzylic becuse here is no benzene ring

So here is only a alkyl halide present where the bromine is attached to sp³ hybridized carbon.
