Hello Sweta,

All heteroatoms with non-bonded electron pairs are candidates for
H-bonding. This includes a long list of functions, the most important of
which are the halogens in organic halides and halide anions, oxygen in
water, and hydroxykic functions such as alcohols, phenols, carboxylic
acids, and duble-bonded functions such as carbon dioxide, carboxylic acids,
esters, aldehydes and ketones, the ethers, etc. The sulfur analogs of the
oxygen functions just mentioned are also H-bond acceptors (electron pair
donors) but weaker; nitrogen atoms holding three bonds (single, double or
triple) to other atoms, such as amines, imines, amides, nitriles, etc. can
also be H-bonded.

All the best,

Jacob
