Question

Which of the following pair has more negative electron gain enthalpy a) O or F. b) F or Cl​

Answer 1

Answer:

b) f or cl

Explanation:

as f is the most electronegative element and cl is most stable electronegative element which makes its electron gain enthalpy more than that of f

Answer 2

Answer:

( ii ) F and Cl

but Chlorine gives highest electron gain enthalpy rather than flourine
