HYDROGEN BOND:
an eletrostatic attraction between the neighbouring molecules is set up when the positive and of one molecule attracts the negative polevof the neighbouring molecule.this type of attractive force which involves hydrogen is referred as hydrogen bond.
EFFECT OF HYDROGEN BOND ON WATER SOLUBILITY
molecules which are capable of hydrogen bond having hydrogen atom with are covalently bonded to highly electronegative elements.the presence of hydrogen bond between molecules indicate that they are only polar and only soluble in polar solvent such as water.

Effect of hydrogen bonding on melting point :. the compounds which have hydrogen bonding show abnormally high melting point . For example liquid water has high no. of hydrogen bonds each molecule relative to its low molecular mass. As these bonds are difficult to break. water has high melting point . 2) solubility: the compounds which can form hydrogen bonds with covalent molecules are soluble in such solvent . For example ammonia shows high water solubility because in it hydrogen bonds are formed between hydrogen molecules of water and ammonia. the intermolecular hydrogen bonding increases solubility in water. While intramolecular hydrogen bonding decreases solubility in water.
