Water structure and hydrophobic bonding

Water possesses many unique feamres that distinguish it from other liquids. These arise from the unusual stmcture of the molecule in which the O and H atoms are arranged at the apices of a triangle (see Fig. 6.22). 

Each of the covalent bonds between a hydrogen atom and the oxygen atom of the water molecule involves the pairing of the electron of the hydrogen atom with an electron in the oxygen atom s outer shell of six 

Most of the models proposed for the stmc-ture of water, only two of which have been considered here, can account for some, but not all of the physical and thermodynamic anomalies which have been observed with water.
