khf2 exist but KHCL2 and khbr 2 does not why

Khf2 is ionic compound with k+ and hf2- but when there is hcl2- ion the anion size become so large than cation size..Overall we can say khf2 exist due to small size of f
saumyatiwari:
i didn't understood it properly
Hf2ion has comparely equal size that of k+ ion whereas hcl2 and hbr2 have large size thats why do not form bond with k+ ion and hence they do not exist..Hope now u understand well..
yes...
thank u..

Welcome dear,
● KHF2 exists but KHCl2 and KHBr2 don't because ?
- Fluorine is more electronegative than that of both Cl and Br.
- Higher electronegativity implies stronger hydrogen bonding, thus F bonds with H to form HF2- ion.
- Therefore, K+ cation combines with HF2- anion to form ionic compound KHF2.
- Due to less electronegativity, Cl and Br can't form HCl2- and HBr2- ions respectively.
Hope this helps you...
