Answer 1

Calculation of hybridization: H = 1/2 [V + M - C + A] or H = no. of lp + b.p. H rightarrow type of hybridization V rightarrow no. of valence depends on central atom M rightarrow no. of monovalent atoms C rightarrow charge on cation, A rightarrow charge on atom lp rightarrow lone pair, bp rightarrow bonded pair H = 2 rightarrow Sp Geometry rightarrow Linear H = 3 rightarrow Sp^2 --------- Triangular planar H = 4 rightarrow Sp^3 --------- Tetrahedral H = 5 rightarrow Sp^3d -------- Trigonal bipyramidal H = 6 rightarrow Sp^3d^2 -------- Octahedral. H = 7 rightarrow Sp^3 d^3 ------- Pentagonal bipyramidal BrF_4^- , H = 1/2 [7 + 4 - 3] = 5 i.e, Sp^3 d Trigonal bipyramidal. Nu_3, H = 1/2 [5 + 3] = 4 i.e, Sp^3 Tetrahedral SbF_5^2- , H = 1/2 [5 + 5 6 2] = 6 i.e, Sp^3 d^2 Octahedral SeCl_4, H = 1/2 [6 + 4] = 5 i.e, Sp^3 d
