Question

Assertion : Addition of HBr on 2-butene gives two isomeric products.

Reason : Addition of HBr on 2-butene follows Markownikoff's rule.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (d) A and R are false

Explanation:

Addition of HBr on 2-butene gives only one product, 2-bromobutane.

As 2-butene is a symmetrical alkene, it does not follow Markownikoff's rule.
