1.	Explain the following(a) The density of ice is less than that of liquid water? (b) The boiling point of water is less than that of H2S. (c) NaH has higher reducing character than H2O.
Answer» a) In a structure of ice, Oxygen atom is tetrahedrally surrounded by four hydrogen (with two hydrogen by the hydrogen bond and with two hydrogen by covalent bond ) and have vacant spaces in which air is trapped b) Due to extensive hydrogen bonding in water c) NaH is ionic compound while water is a covalent compound
