Concept explainers
(a)
Interpretation:
The cyclic (or) multiple bond structure should be drawn given the molecular formula of compounds.
Concept introduction:
Molecular formulas formula of a compound is one which expresses the actual number of each kind of atom present in its molecule.
For example the molecule of ethane is consisted of two carbon atoms, 6 hydrogen atoms which give the molecular formula of ethane as
Cyclic compounds: The cyclic compounds are organic compounds in which a series of atoms (generally carbon, oxygen or nitrogen) form a ring. The minimum amount of atoms required to make a ring is must three.
Conjugated systems: Molecule has a conjugated system if it has alternating double bonds, lone pairs in p-orbital are also considered part of conjugated system.
(b)
Interpretation:
The cyclic (or) multiple bond structure should be drawn given the molecular formula of compounds.

Concept introduction:
Linear molecule: This molecule is electron deficient and does not follow the octet rule it has only four electrons, the hydrogens atoms are as far apart as possible if opposite each other at 1800 it is a linear molecule.
