Assertion : Addition of HBr on 2-butene gives two isomeric products. Reason : Addition of HBr on 2-butene follows Markovnikov's rule.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of the assertion
  3. CIf assertion is true, but reason is false
  4. DBoth assertion and reason are false statements.

Correct answer

D. Both assertion and reason are false statements.

Step-by-step solution

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.
