rmation in sf4 by using the concept of HYBRIDIZATION:First we have to find out the hybridization of given molecule by using below steps 1)find the total number of VALANCE electrons for sf4Here 6 valance e⊕ in "s" and 7 valance e⊕ in "f" atom.Total valance electrons=6+4*7                                       =6+28                                       =342)Divide the total valance electrons by 2 (If the total valance electron is less than 8 and if the total valance electron is grater than 8 then we have to divide it by 8).if any semiconductor we can consider it as by .we get the steric number is 4H=5 3)then assign the hybridization ACCORDING to the steric number                 Steric number                 Hybridization                            2                                       sp                            3                                       sp^2                            4                                       sp^3                            5                                       sp^3d                            6                                       sp^3d^2Bond formation in ccl4 by using hybridization concept:1)first we have to find the hybridization of ccl4                                =4+4                                 =82)Divide the total valance electron by 2 we get                                              =8/2                                              =43)Assign the hybridization according to steric numberwe get hybridization of sp^3Then the geometry is tetrahedralAnd shape also tetrahedral
