Among the following, choose the correct products that are formed in the reaction of $\mathrm{S}_{2} \mathrm{Cl}_{2}$ with ammonia in $\mathrm{CCl}_{4} \mathrm{NH}_{4} \mathrm{Cl}(\mathrm{A}), \mathrm{S}_{4} \mathrm{N}_{4}(\mathrm{B}), \mathrm{S}_{8}(\mathrm{C})$, and $\mathrm{S}_{3} \mathrm{N}_{3} \mathrm{Cl}_{3}(\mathrm{D})$.
(a)A, B and C
(b)A, B and D
(c)B, C and D
(d)A, C and D
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
6S₂Cl₂ + 16NH₃ → S₄N₄ + S₈ + 12NH₄Cl — the classical S₄N₄ synthesis gives A, B and C (S₃N₃Cl₃ is made from S₄N₄ + Cl₂).
