Options
- AX is used for sterilizing drinking water.
- BY has a planar structure.
- CZ is used in the enrichment of ²³⁵ U .
- DY is a stronger Lewis base than ammonia.
Correct answer
A. X is used for sterilizing drinking water.
Step-by-step solution
From the given reactions, we can identify the compounds X , Y , and Z as follows: Reaction 1: MnO ₂ + 4 HCl (conc.) MnCl ₂ + Cl ₂ + 2 H ₂ O The greenish-yellow gas X is Cl ₂ . Reaction 2: NH ₃ + 3 Cl ₂ (excess) NCl ₃ + 3 HCl Compound Y is NCl ₃ . Reaction 3: Cl ₂ + 3 F ₂ (excess) 573 K 2 ClF ₃ Compound Z is ClF ₃ . Evaluating the given statements: (A) Cl ₂ is widely used as a disinfectant for sterilizing drinking water. This statement is correct. (B) In NCl ₃ , the nitrogen atom is sp^3 hybridized and possesses one
