  2. Statement I is incorrect but Statement II is correct
  3. Both Statement I and Statement II are correct
  4. Both Statement I and Statement II are incorrect

Answer

(3) Both Statement I and Statement II are correct

Solution

Statement-I: As per NCERT, benzenediazonium chloride is prepared by the reaction of aniline with nitrous acid (NaNO2 + HCl) at 273–278 K:

C6H5NH2 + NaNO2 + 2HCl 273-278 K C6H5N2+Cl- + NaCl + 2H2O

NCERT also states that it is stable in cold solution but decomposes easily in the dry state. Correct.

Statement-II: As per NCERT, iodine is not easy to introduce into the benzene ring directly, but iodobenzene is formed when the diazonium salt solution is treated with KI:

C6H5N2+Cl- + KI C6H5I + KCl + N2. Correct.

Answer: (3)
