The shape of H2O molecule is bent while that of CO2 is linear. The correct explanation for this fact is that dipole moment of:

1. carbon dioxide is 3.84 D and that of water is zero.
2. water is zero and that of carbon dioxide is 1.84 D.
3. carbon dioxide is zero and that of water is 1.84 D.
4. carbon dioxide is 3.84 D and that of water is 1.84 D.

The application of dipole moment is/are :

1. It is used to differentiate polar and non-polar bonds.
2. It is helpful in calculating the percentage ionic character of a molecule.
3. Both '1' and '2'
4. None of the above.

The correct order of increasing ionic character in the molecules: LiF, K2O, N2, SO2 and ClF3 is:

1. N2  < ClF3 < SO2< K2O < LiF

2. N2  < ClF3  < LiF < SO2< K2O

3. SO2< K2O < ClF3  < LiF < N2

4. N2 < SO2 < ClF3 < K2O < LiF

 BeH2 molecule has a zero dipole moment because -

1.

Dipole moments of each H–Be bond are unequal and are in opposite directions.

2. Dipole moments of each H–Be bond are equal and are in opposite directions.
3. Dipole moments of each H–Be bond are equal and are in same directions.
4. Dipole moments of each H–Be bond are unequal and are in same directions.
