Question

$KH{F}_2$ is stable and exists unlike $KHB{r}_{2}andKH{I}_2$ reason is _____

• A. Inter-molecular H-bonding
• B. Intra molecular H-bonding
• C. Covalent bonding
• D. Ionic bonding

Answer 1

The correct option is A

Inter-molecular H-bonding

$InKH{F}_2,KH{F}_2------H{F}_{2}K$ intermolecular H-bonding is possible. This is not in KHBr₂ or KHI₂. Because of big size of Br and I

Thus, only $KH{F}_2$ exists
