The bond energies (in kJ mol ⁻¹ ) of P - H , As- - H and N - H are respectively

Options

  1. A247,389 and 318
  2. B247,389 and 318
  3. C318,389 and 247
  4. D318,247 and 389

Correct answer

D. 318,247 and 389

Step-by-step solution

Decreasing order of these hydrides is N - H > P - H > As - H Bond energies 389>318>247 (decreases with increase in bond lengths)
