When will hydrogen bonding occur?Give an example of liquid other than H2O in which this type of force is important.
In order for a hydrogen bond to occur there must be both a hydrogen donor and an acceptor present. The donor in a hydrogen bond is the atom to which the hydrogen atom participating in the hydrogen bond is covalently bonded, and is usually a strongly electronegative atom such as N,O, or F. The hydrogen acceptor is the neighboring electronegative ion or molecule, and must posses a lone electron pair in order to form a hydrogen bond.An example is NH3. Hydrogen bonding is responsible for ammonia's remarkably high solubility in water. thanks
