The correct order of bond enthalpy of given molecules is

Options

  1. AO ₂ < N ₂ < H ₂
  2. BN ₂ < O ₂ < H ₂
  3. CH ₂ < N ₂ < O ₂
  4. DH ₂ < O ₂ < N ₂

Correct answer

D. H ₂ < O ₂ < N ₂

Step-by-step solution

The correct order of bond enthalpy = H ₂ < O ₂ < N ₂ This is due to increasing bond strength due to single, double and triple bonds respectively ( H - H , O = O , N N).
