Question

How do you express the bond strength in terms of bond order ?

Define the bond length.

Apart from tetrahedral geometry, another possible geometry for CH4 is square planar with the four H atoms at the corners of the square and the C atom at its centre. Explain why CH4 is not square planar ?

Arrange the following as stated: (i) N2, O2, F2, Cl2 (Increasing order of bond dissociation energy) (ii) F, Cl, Br, I (Increasing order of electron gain enthalpy) (iii) F2, N2, Cl2, O2 (Increasing order of bond length)
