Options

  1. ANOandN2ONOand{N}_{2}O
  2. BNO2andN2ON{O}_{2}and{N}_{2}O
  3. CN2OandNO2{N}_{2}OandN{O}_{2}
  4. DNO2andNON{O}_{2}andNO

Correct answer

C. N2OandNO2{N}_{2}OandN{O}_{2}

Step-by-step solution

ZnZn on reaction with HNO3HN{O}_{3}

4Zn+10HNO3→4Zn(NO3)2+N2O+5H2O4Zn + 10HN{O}_{3} \to 4Zn{\left(N{O}_{3}\right)}_{2} + {N}_{2}O + 5{H}_{2}O
(Dil.)
Zn+4HNO3→Zn(NO3)2+2NO2+2H2OZn + 4HN{O}_{3} \to Zn{\left(N{O}_{3}\right)}_{2} + 2N{O}_{2} + 2{H}_{2}O
