Question

HF2-exists but HCl2-not exists _explain why

Answer 1

Hey mate here is the answer to your question

The existance depends upon the electronagtivity present between both of them so two factor depend

1: is size of element 2: electronegtivity between them

So if more electronegtive atom hence having more polar bond as F

Smaller size shows more stronger bond so HF exist

hope this answer will be helpful.
