Why is KHF a known salt, but KHCI is not?
Option: 1
Fluorine is more electronegative than chlorine, so it can form stronger hydrogen bonds with potassium.
Option: 2
Chlorine is larger than fluorine, so it cannot fit into the crystal lattice of potassium fluoride.
Option: 3
Fluorine is more reactive than chlorine, so it reacts more readily with potassium hydroxide.
Option: 4
Chlorine is more stable than fluorine, so it does not form hydrogen bonds as easily.
Answers (1)
Due to higher electronegativity and small size of fluorine, it is capable of forming H-bond resulting in the formation of HF, and thereby KHF; exists. But with chlorine, there is no possibility of H-bonding, so there is no possibility of existence of KHCI
