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.
Geometry of different types of molecule with respect to the hybridizations is mentioned are mentioned below,
(d)
Interpretation:
Hybridization of nitrogen atom in the molecule has to be given.
Concept Introduction:
Refer to (c).
(e)
Interpretation:
Hybridization of hydrogen bearing carbon atoms in the molecule has to be given.
Concept Introduction:
Refer to (c).
