Give the shape of molecule in which only bonding pair is present.

1.	Give the shape of molecule in which only bonding pair is present.
Answer» Solution :For the prediction of GEOMETRICAL shapes of molecules with the help of VSEPR theory, it is CONVENIENT to divide molecules into two categories as (i) Molecules in which the central atom has no lone pair and (II) Molecules in which the central atom has one or more lone pairs. The following table shows the arrangement of electron pair about a central atom A (without any lone pairs) and geometries of some molecules/ions of the TYPE AB.
