Question

why cl2 do not have repulsion??​

Answer 1

Explanation:

ANSWER

Bond dissociation energy of F

2

molecule is less than that of Cl

2

molecule because F has smaller radius and due to smaller size repulsion is high.

Both have 3 lone pairs but in the case of chlorine the lone pairs have more space to be in, leading to a lower stress on the bond. In flourine however the lone pairs have less space to be in, adding stress on the bond making its easier to break.
