Question

which compound of halogen exibit hydrogen bonding?

Answer 1

Halocarbon exhibit hydrogen bonding.

Answer 2

Hydrogen bond is formed only by the 3 highly electronegative elements- fluorine, oxygen and nitrogen.

So, hydrogen bonding is possible only in those compounds in which the hydrogen atom is directly bonded to fluorine, oxygen or nitrogen. In other words, hydrogen bonding occurs only in compounds having the highly polar F-H, O-H or N-H bond in their molecules.

Examples of such molecules are HF, H2O, NH3(in liqiud state), C2H5OH (ethanol) and other alcohols, and carboxylic acids like CH3COOH (acetic acid)
