Question

One of the following which does not observe the anti-Markownikoff's addition of HBr,

Answer 1

These are the HBr addictions that are not observed

Propene

Butene

But-2-ene

Pent-2-ene

Also, Anti-Markownikoff's addition of HBr is observed only with unsymmetrical alkenes (i.e) propene,1-butene,pent-2-ene.As 2-butene is symmetrical so in its case anti-Markownikoff's addition will not be observed.

Hence (c) is the correct answer.
