Read the passage given below and answer the following questions:
Benzene ring in aniline is highly activated. This is due to the sharing of lone pair of nitrogen with the ring which results in increase in the electron density on the ring and hence facilitates the electrophilic attack. The substitution mainly takes place at ortho and para positions because electron density is more at ortho and para positions. On reaction with aqueous bromine all the ortho and para positions get substituted resulting in the formation of 2,4,6-tribromoaniline. To get a monobromo compound, the amino group is acetylated before bromination. After bromination, the bromoacetanilide is acid hydrolysed to give the desired halogenated amine.
In the following questions, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices :
Assertion (A): The amino group of aniline is acetylated before bromination.
Reason (R): It is due to the strong deactivating effect of –NH2 group.
  • a)
    Assertion and reason both are correct statements and reason is correct explanation for assertion.
  • b)
    Assertion and reason both are correct statements but reason is not correct explanation for assertion.
  • c)
    Assertion is correct statement but reason is wrong statement.
  • d)
    Assertion is wrong statement but reason is correct statement.
Correct answer is option 'C'. Can you explain this answer?

Read the passage given below and answer the following questions:Benze...

Explanation:

Assertion and Reason Analysis:

- The assertion states that the amino group of aniline is acetylated before bromination.
- The reason given is that this is due to the strong deactivating effect of the -NH2 group.

Explanation:

- Acetylation of the amino group in aniline is done to prevent the strong activating effect of the amino group.
- The amino group in aniline is highly activated and directs substitution mainly at ortho and para positions due to the increase in electron density on the benzene ring.
- However, if bromination is carried out directly, multiple substitutions can occur leading to the formation of 2,4,6-tribromoaniline.
- Acetylation of the amino group deactivates it, making it less reactive towards electrophilic substitution, thus allowing for the selective monosubstitution of the benzene ring.
- After acetylation and bromination, the bromoacetanilide is then hydrolyzed to obtain the desired halogenated amine.

Conclusion:

- The assertion is a correct statement because acetylation of the amino group is indeed carried out before bromination.
- The reason is a wrong statement because it mentions the strong deactivating effect of the -NH2 group, which is contrary to the actual purpose of acetylation in this context.
