The dipole moment of compound AB is 10.92 D and that of compound CD is 12.45 D. If the bond length of AB is 2.72 A° and that of CD is 2.56 A°, then for these compounds the correct statement is:

1. More ionic nature in AB 2. More ionic nature in CD
3. Equal in both 4. Cannot be predicted

Find the correct reason for H₂O being polar while BeF₂ is non-polar.

1. H₂O shows hydrogen bonding, whereas BeF₂ exists as a discrete molecule.
2. H₂O is linear, whereas BeF₂ is angular.
3. H₂O is angular, whereas BeF₂ is linear.
4. The electronegativity of F is greater than that of O
