The correct order of electron gain enthalpy of N , O , Cl , Al is

Options

  1. ACl < N < O < Al
  2. BAl < N < O < Cl
  3. CO < N < Al < Cl
  4. DN < O < Cl < Al

Correct answer

B. Al < N < O < Cl

Step-by-step solution

Correct order of electron gain enthalpy:- Al < N < O < Cl It is higher for non-metallic elements that have higher electronegativities (higher in magnitude)
