Hydrogen+Bonding

Hydrogen Bonding


 * Hydrogen bonding is an extreme case of temporary dipole-dipole movement.
 * It is the intermolecular attraction between hydrogen atom which is covalently bonded to a highly electronegative atom like N,O,F and the lone pair of another highly electronegative atom.
 * The density of ice is less than water as hydrogen bonding in ice results in an open rigid 3D tetrahedral structure which holds the water molecules further apart in solid than in liquid.Hence ice has a larger volume and lower density than water.
