Question

Which of the following has least electron gain enthalpy? A) sulpur B) chlorine C) Flourine D) oxygen

Answer 1

Answer:

A)

Explanation:

Sulphur

I think so but not too sure

Answer 2

Explanation:

We know,Halogens have highest negative value of electron gain enthalpy. Here Cl and F both are halogens but electron gain enthalpy of Cl is more negative than F because of very small size of F which causes interelectronic repulsion among its electrons.

Cl has the most negative one.

P has the less negative one due to larger size..
