  • valence electrons of S = 6

    electrons given by Cl3 = 3

    electrons given by F = 1

    total no of electrons = (6+3+1) = 10

    no of electron pairs = 10/2 = 5

    no of bond pairs with CL an F = (3+1) = 4

    no of lone pairs = 5-4 = 1

    therefore molecular shape is = see-saw

  • C. SeeSaw

    U= 1/2 (B-A)

    B=6(N)+2 *N=#atoms not counting Hydrogen

    A=all available valence e-

    A: add 1 for each - charge, subtract 1 for each + charge

    U=O

    5 Atoms = Tetrahedral i.e. CH4

    4 Atoms=Trigonal Pyramidal

    3 Atoms = Angular (bent)

    2 Atoms=linear

    U=1

    4 Atoms=Trigonal Planar

    3 Atoms=Angular Bent

    2 Atoms=Linear

    U=2

    Linear

    U=-1

    6 atoms =Trigonal Bipyramidal

    5 atoms=Seesaw(i.e. SCl3F)

    4 atoms=T-shaped

    3 atoms=Linear

    U=-2

    7atoms=Octahedral

    6 atoms=Square Pyramidal

    5 Atoms=Square Planar
