Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R

Assertion (A) : Trans-2-butene on reaction with $Br _{2}$ gives meso-2,3-dibromobutane.

Reason (R) : The reaction involves $syn-addition$ of bromine.

In the light of the above statements, choose the correct answer from the options given below

• 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 and the reason is not the correct explanation of the assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

If assertion is true but reason is false

Answer 2

With trans-$2$-butene, the product of $Br_2$ addition is optically inactive due to the formation of symmetric meso compounds.
