A) Addition of HBr on 2-butene gives two isomeric products.
R) Addition of HBr on 2-butene follows Markownikoff's rule.

Options

A. if both Assertion and Reason are true and reason is the correct explanation of the assertion.
B. if both assertion and reason are true but reason is not the correct expalanation of the assertion
C. if assertion is true, reason is false
D. both assertion and reason are false statements.

Answer

d

Explanation

Addition of HBr on 2- butene gives only one product, 2 - bromobutane.
`CH_(3)-underset(2-"butane")(CH=CH-CH_(3)) overset(HBr) to CH_(3)-underset(2-"Bromobutane")underset(Br)underset(|)(CH-CH_(2)-CH_(2))`
As 2- butene is a symmetrical alkene, it does not follow Markownifoff's rule.
