NCERT QUESTIONS

Chemical Bonding and Molecular Structure

 

Que 1. Although geometries of NHand H2O molecules are distorted tetrahedral, bond angle in water is less than that of ammonia. Discuss.

 

Que 2. Explain the important aspects of resonance with reference to the CO32-ion.

 

Que 3. Although both CO2 and H2O are triatomic molecules, the shape of H2O molecule is bent while that of CO2 is linear. Explain this on the basis of dipole moment.

Que 4. Explain with the help of suitable example polar covalent bond.

Que 5. Arrange the bonds in order of increasing ionic character in the molecules: LiF, K2O, N2, SO2 and ClF3.
