KHF_(2) is known but KHCl_(2)is not known. Gove reasons.

Answer»

Solution :SINCE F is much more ELECTRONEGATIVE than Cl, therefore, HF forms hydrogen bonding with `F^(-)` of KFto FORM `KHF_(2)`, i.e.,
`K^(+) F^(-) HF rarr K^(+) (F^(-) ........ H-F) or KHF_(2)`
bit HCl does not form H-bonding with `Cl^(-)` of KCl to form salt of the type `KHCl_(2)`
