NEET Chemistry Substitution Reactions Assertion Reason Question
Assertion (A): Chlorination of benzene in the presence of anhydrous AlCl3 can lead to hexachlorobenzene when excess chlorine is used.
Reason (R): During chlorination, the electrophile is generated, which allows successive replacement of hydrogen atoms in benzene.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
Both the assertion and reason are true. The NCERT context explains that when benzene is treated with excess chlorine in the presence of anhydrous AlCl3, hexachlorobenzene is formed through successive substitution reactions, facilitated by the generation of the electrophile.
