Which out of the two molecules - OCS and CS₂ has a higher dipole moment and why ?

Discuss the applications (or importance) of dipole moment.

The molecule of SO₂ has a dipole moment. Is the molecule linear or bent? Explain your answer.

Predict the dipole moment of;
(i) a molecule of the type AX₄ having a square planar geometry.
(ii) a molecule of the type AX₅ having a trigonal bipyramdial.
(iii) a molecule of the type AX₆ having an octahedral geometry.

Which of the two - NH₃ and NF₃ has higher dipole moment and why?

What do you understand by resonance?

207.

Discuss the resonance in CO₂ and O₃molecule.

Write the resonance structures for SO₃,   NO₂ and 

Write the resonance structure for:
(i) Benzene (C₆H₆)
(ii) Carbonate ion (CO₃^–)

What is resonance enthalpy? What is its significance?
