Concept explainers
(a)
Interpretation:
Sigma bonds in the molecule have to be located and have to be counted.
Concept Introduction:
Sigma (σ) bonds are the bonds in which shared hybrid orbital’s electron density are concentrated along the internuclear axis.
(b)
Interpretation:
Pi bonds in the molecule have to be located and have to be counted.
Concept Introduction:
Pi (π) bonds are the bonds in which shared un-hybridized orbital’s (p, d, etc) electron density are concentrated in above and below the plane of the molecule.
(c)
Interpretation:
Hybridization of carbon atom that is bonded to the nitrogen atom in the molecule has to be given.
Concept Introduction:
Hybridization is the mixing of valence atomic orbitals to get equivalent hybridized orbitals that having similar characteristics and energy.
