Assertion and Reason Analysis:
Assertion and Reason questions require careful analysis to determine the relationship between the two statements. Let's break down the given Assertion and Reason in this question.
Assertion:
Trans-2-butene on reaction with Br2 gives meso-2, 3-dibromobutane.
Reason:
The reaction involves syn-addition of bromine.
Explanation:
Assertion Justification:
Trans-2-butene is a symmetrical alkene with a trans configuration. When it undergoes addition reaction with Br2, the bromine atoms add to the same side of the double bond, resulting in meso-2,3-dibromobutane. This is possible due to the symmetrical nature of the alkene molecule.
Reason Justification:
The term "syn-addition" refers to the addition of two substituents to the same side of a double bond. In the case of the reaction of trans-2-butene with Br2, the bromine atoms are added syn to each other, leading to the formation of meso-2,3-dibromobutane. This demonstrates the concept of syn-addition in organic chemistry reactions.
Conclusion:
The correct answer is option 'C', where the Assertion is true as the given reaction indeed yields meso-2,3-dibromobutane, but the Reason is false as it incorrectly states that the reaction involves syn-addition, whereas it actually involves anti-addition.

The assertion that trans 2-butene reacts with Br2 to produce meso 2, 3-dibromo butane is correct but it does not involve syn–addition.
