Detailed Solution
Number of electron pairs(EP)=V+M-C+A2; V=Group number of central atom; M=-H, -X, -OH....monovalent groups attached to central atom ; C=Charge of cation ; A=Charge of anion ; V=2,3,4,5,6,7,8 respectively for 2nd , 13th, 14th,15th, 16th, 17th, 18th group elements ; Number bond pairs, BP(according to VSEPR theory)=Number of atoms directly attached to central atom; =4,3,2 respectively in CH4(CX4), NH3( PX3 ), H2O ; Number lone pairs on central atom(LP)=EP-BP ; =0,1,2 respectively in CH4(CX4), NH3 ( PX3 ), H2O ; NH3(NX3)....PX3,AsX3,SbX3,BiX3,-'3' bp +'1' lp on central atom ; sp3-Pyramidal ; RX3---10 lone pairs/molecule--9 lone pairs on bonded atoms--R--15th group element ;
