VSEPR theory predicts the shapes of the molecules. The other methods of determining the shapes of the molecules are by hybridizations technique and dipole moment of the molecules.If A represents the total number of hybrid orbitals, P represents total number of valence electrons, then A = P – 3 (number of atoms surrounding the central atom excluding H-atom)
The number of bond pairs
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
(i)
Sol. Cl atom has 7 valence electrons 3 are used for bonding and 4 are left hence number of bond pairs; b = 3, number of lone pairs; n = 2. Thus XS 3 E 2
(ii)
Sol. CO 2 molecule is linear 
, μ R = 0 (No net dipole)
very less resultant dipole moment ( μ R is very less)
very high resultant dipole moment ( μ R is very high)
(iii)
Sol. In CH ≡ CH each C – atom is sp hybridized and all atoms lie in one plane
