(a)
Interpretation:
The electron-pair geometry for each carbon and nitrogen atoms in the molecule
Concept introduction:
The electron pairs in Lewis diagrams repel each other in real molecule and thus they distribute themselves in positions around the central atoms which are far away from one another. This arrangement of electron pairs is called electron-pair geometry. The electron pairs may be shared in covalent bond, or they may be lone pairs.
Answer to Problem 28E
The Lewis diagram for the molecule
The electron pair geometry for the carbon
Explanation of Solution
To write the Lewis diagram for a compound first the number of valence electrons is to be calculated. In the molecule

(b)
Interpretation:
The molecular geometry predicted by the valence shell electron-pair repulsion theory for each carbon and nitrogen atoms in the molecule
Concept introduction:
Molecular geometry is the precise term that is used to describe the shape of molecules and arrangement of atoms around the central atom. The molecular geometry of a molecule is predicted by valence shell electron-pair repulsion theory or in short VSEPR theory. VSEPR theory applies to substances in which a second period element is bonded to two, three, four, or other atoms.
