Q46. Match List-I with List-II:
List-I
(A) Ammonia
(B) Nitric Acid
(C) Phosphene
(D) White Phosphoru

Q: What is the correct answer for CUET UG Chemistry Q46?

The correct answer is a. (A) Ammonia (NH3) is used in qualitative analysis for the detection of many metal ions (e.g., Cu2+, Fe3+) through the formation of hydroxides or complex ions. So (A)-(II).(B) Nitric acid (HNO3) is produced industrially by the Ostwald process, involving the catalytic oxidation of ammonia. So (B)-(IV).(C) Phosphine (PH3) is a highly toxic gas known for its characteristic odor, often described as 'ro

(A) Ammonia (NH3) is used in qualitative analysis for the detection of many metal ions (e.g., Cu2+, Fe3+) through the formation of hydroxides or complex ions. So (A)-(II).(B) Nitric acid (HNO3) is produced industrially by the Ostwald process, involving the catalytic oxidation of ammonia. So (B)-(IV).(C) Phosphine (PH3) is a highly toxic gas known for its characteristic odor, often described as 'rotten fish smell'. So (C)-(I).(D) White phosphorus exhibits chemiluminescence (glowing in the dark) upon slow oxidation in moist air. So (D)-(III).Thus, the correct match is (A)-(II), (B)-(IV), (C)-(I), (D)-(III).
