Addition of HBr on 2-butene gives only one product, 2-bromobutane. As 2-butene is a symmetrical alkene, it does not follow Markovnikov's rule. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/160f58375f84f0fd215bec12c90a87d1-.png" />

Q. Assertion : Addition of $H B r$ on $2$ -butene gives two isomeric products.
Reason : Addition of $H B r$ on $2$ -butene follows Markovnikov’s rule.

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

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

If assertion is true, but reason is false

Both assertion and reason are false statements
