NEET2018Chemistryp Block Elements (Group 15, 16, 17 & 18)Actual
The correct order of N - compounds in its decreasing order of oxidation states is
Options
- AHNO 3 ,   NH 4 Cl ,   NO ,   N 2
- BHNO 3 ,   NO ,   NH 4 Cl ,   N 2
- CHNO 3 ,   NO ,   N 2 , NH 4 Cl
- DNH 4 Cl ,   N 2 ,   NO ,   HNO 3
Correct answer
C. HNO 3 ,   NO ,   N 2 , NH 4 Cl
Step-by-step solution
→ HNO 3 ⇒ 1 + x + 3 ( − 2 ) = 0 x = 5 → NO ⇒ x + 1 ( − 2 ) = 0 x = 2 → N 2 ⇒ 2 x = 0 x = 0 → NH 4 Cl = x + 4 ( 1 ) + 1 ( − 1 ) = 0 x = − 3
