Question

Which of the following pair of elements would have more electron gain enthalpy..? F or Cl? Explain.​

Answer 1

Explanation:

But electron gain enthalpy of Cl is higher than F . This is because , size of F is small due to this , the electron - electron repulsion in relatively compact 2p- orbital is greater than in the larger 3p-orbital and hence, incoming electron feels greater repulsion in fluorine than in chlorine
