Directions: These questions consist of two statements, each printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses.



Assertion : SN2 reaction of an optically active aryl halide with an aqueous solution of KOH always gives an alcohol with opposite sign of rotation.

Reason : SN2 reactions always proceed with inversion of configuration.

  • a)
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

  • b)
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

  • c)
    If the Assertion is correct but Reason is incorrect.

  • d)
    Assertion is false and Reason are true

Correct answer is option 'D'. Can you explain this answer?

Assertion is false, because aryl halides do not undergo nucleophilic substitution under ordinary conditions. This is due to resonance, because of which the carbon– chlorine bond acquires partial double bond character, hence it becomes shorter and stronger and thus cannot be replaced by nucleophiles. However Reason is true.

Explanation:

The given Assertion and Reason are related to the SN2 reaction of an optically active aryl halide with an aqueous solution of KOH. Let's analyze each statement separately:

Assertion:

SN2 reaction of an optically active aryl halide with an aqueous solution of KOH always gives an alcohol with opposite sign of rotation.

This assertion is incorrect. The sign of rotation of an optically active compound depends on the absolute configuration of its chiral centers. In the case of SN2 reaction of an optically active aryl halide, the absolute configuration of the chiral center is not changed, and the sign of rotation of the product will be the same as that of the reactant.

Reason:

SN2 reactions always proceed with inversion of configuration.

This reason is correct. SN2 reactions involve the attack of a nucleophile on the backside of the leaving group, resulting in the inversion of the configuration at the chiral center. This is because the nucleophile has to approach the chiral center from the opposite side of the leaving group, which leads to the inversion of the configuration.

Therefore, the correct answer is option 'D' - Both the Assertion and Reason are incorrect.
