Assertion: 1-Butene on reaction with HBr...

Assertion`:` `1-`Butene on reaction with `HBr` in the presence of a peroxide produces `1-`bromo`-`butane
Reason`:` It involves the free radical mechanism.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

A
This reaction takes place against Markownikoff's rule

In this reaction anti`-` Markownikoff's addition is explained on the basis of the fact that in the presence of peroxide the addition takes place via a free radical meachnism.
