Correct statement(s) about the compounds X, Y and Z is(are) MnO_2 + Conc. HCl ⟶ MnCl_2 + X (greenish yellow gas) + H_2O NH_3 + X (excess) ⟶ Y + HCl X + F_2 (excess) 573 K Z

JEE Advanced 2026 Chemistry question

Correct statement(s) about the compounds X, Y and Z is(are) + Conc. HCl ⟶ + X (greenish yellow gas) + + X (excess) ⟶ Y + HCl X + (excess) Z

(A)X is used for sterilizing drinking water.Correct
(B)Y has a planar structure.
(C)Z is used in the enrichment of ²³⁵U.Correct
(D)Y is a stronger Lewis base than ammonia.

Answer: (A),(C)

Solution

X = Cl₂ (greenish-yellow), used to sterilise drinking water (A true). With excess Cl₂, ammonia gives Y = , which is pyramidal (B false) and, with electron-withdrawing Cl
