The correct order of N−N -compounds in its decreasing order of oxidation states isThe correct order of N - compounds in its decreasing order of oxidation states is

Options

  1. AHNO3,NH4Cl,NO,N2{HNO}_{3}, {NH}_{4}Cl, NO, {N}_{2}
  2. BHNO3,NO,NH4Cl,N2{HNO}_{3}, NO, {NH}_{4}Cl, {N}_{2}
  3. CHNO3,NO,N2,NH4Cl{HNO}_{3}, NO, {N}_{2}, {NH}_{4}Cl
  4. DNH4Cl,N2,NO,HNO3{NH}_{4}Cl, {N}_{2}, NO, {HNO}_{3}

Correct answer

C. HNO3,NO,N2,NH4Cl{HNO}_{3}, NO, {N}_{2}, {NH}_{4}Cl

Step-by-step solution

The correct order of N - compounds in its decreasing order of oxidation states is

→HNO3⇒1+x+3(−2)=0\to {HNO}_{3} ⇒ 1 + x + 3( - 2 ) = 0

x=5x = 5

→NO⇒x+1(−2)=0\to NO ⇒ x + 1( - 2 ) = 0

x=2x = 2

→N2⇒2x=0\to {N}_{2} ⇒ 2x = 0

x=0x = 0

→NH4Cl=x+4(1)+1(−1)=0\to {NH}_{4}Cl = x + 4( 1 ) + 1( - 1 ) = 0

x=−3x = - 3
