1.	What do you understand by bond pairs and lóne pairs of electrons? Illustrate by giving one example of each type.
Answer» Solution :The electron pair involved in sharing between two atoms during covalent BONDING is CALLED SHARED pair or bond pair. At the same time, the electron pair which is not involved in sharing is called lone pair of electrons. For example, In `CH_(4),[Hunderset(H)UNDERSET(* )OVERSET(H)overset( *)C:H]` there are only 4 bond pairs, but in `H_(2)O,` there are two bond pairs and two lone pairs.
