Which of the following statements are correct?
I. In nitrating mixture nitric acid participates as an acid.
II. \(\sigma\) complex is the intermediate substance in electrophilic substitution of benzene.
III. Benzene on Friedel-Crafts alkylation with n-propyl chloride gives isopropyl benzene.
- A II, III only
- B I, II only
- C I, III only
- D I, II, III
Answer & Solution
Correct Answer
(A) II, III only
Step-by-step Solution
Detailed explanation
(I) In nitrating mixture, nitric acid \(\left(\mathrm{HNO}_3\right)\) partcipates as an acid is not a correct statement, as \(\mathrm{HNO}_3\) in nitrating mixture (with \(\mathrm{H}_2 \mathrm{SO}_4\) ) behaves as a base. (II) Sigma complex is the intermediate substance in…
