Assertion : Aniline does not undergo Friedel-Crafts reaction.
Reason : –NH2 group of aniline reacts with AlCl3 (Lewis acid) to give acid-base reaction.
  • 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)
    If both the Assertion and Reason are incorrect.
Correct answer is option 'A'. Can you explain this answer?

Aniline does not undergo Friedel craft's reactions because the reagent AlCl3 ​ (the Lewis acid which is used as a catalyst in friedel crafts reaction), being electron deficient acts as a Lewis base. and attacks on the lone pair of nitrogen present in aniline to form an insoluble complex which precipitates out and the reaction does not proceed.

Assertion: Aniline does not undergo Friedel-Crafts reaction.
Reason: –NH2 group of aniline reacts with AlCl3 (Lewis acid) to give acid-base reaction.

Explanation:
The Friedel-Crafts reaction is a type of electrophilic aromatic substitution reaction that involves the addition of an electrophile to an aromatic ring. However, aniline does not undergo the Friedel-Crafts reaction due to the presence of the amino group (-NH2) attached to the benzene ring.

Reasoning:
The reason provided in the question states that the amino group (-NH2) of aniline reacts with AlCl3 (Lewis acid) to give an acid-base reaction. This is a correct statement as AlCl3 is a Lewis acid and can act as an electron pair acceptor. The amino group of aniline can donate a lone pair of electrons to form a coordinate bond with AlCl3, resulting in an acid-base reaction.

However, the reason does not provide a correct explanation for the assertion. The primary reason why aniline does not undergo the Friedel-Crafts reaction is due to the presence of the amino group, which is a strong activating group. The amino group activates the benzene ring towards nucleophilic attack, making it more reactive towards nucleophilic aromatic substitution reactions rather than electrophilic aromatic substitution reactions like the Friedel-Crafts reaction.

In the Friedel-Crafts reaction, the electrophile attacks the aromatic ring to form a new carbon-carbon bond. However, the amino group of aniline activates the benzene ring towards nucleophilic attack, leading to side reactions and multiple substitution products. Therefore, the presence of the amino group in aniline inhibits the Friedel-Crafts reaction.

Conclusion:
Based on the above explanation, we can conclude that the assertion is correct, as aniline does not undergo the Friedel-Crafts reaction. However, the reason provided is partially correct but does not provide a correct explanation for the assertion. Therefore, the correct answer is option 'A'.
