Among the hydrides of the oxygen family why water is different from the other hydrides? Mention all the exceptional behaviour.​

Answer»

The oxygen has high electronegativity. Hence the O-H bond in H2O forms STRONG intermolecular HYDROGEN bonds. As a result, water exist as an associated molecule. ... Thus, water shows unusual physical properties such as high thermal stability, high b.p., weaker acidic character as compared to the other HYDRIDES of group 16.Explanation:Three basic types of hydrides—saline (ionic), metallic, and covalent—may be distinguished on the basis of type of chemical bond involved. A fourth type of hydride, dimeric (polymeric) hydride, may ALSO be identified on the basis of STRUCTURE (see borane).
