(a)
Interpretation:
Whether or not secondary and tertiary carbon atoms are present in the structures given has to be indicated.
Concept Introduction:
In a hydrocarbon structure, each and every carbon atoms are classified as primary, secondary, tertiary, and quaternary carbon atom.
If a carbon atom in an organic molecule is directly bonded to only one another carbon atom is known as primary carbon atom.
If a carbon atom in an organic molecule is directly bonded to two other carbon atoms is known as secondary carbon atom.
If a carbon atom in an organic molecule is directly bonded to three other carbon atoms is known as tertiary carbon atom.
If a carbon atom in an organic molecule is directly bonded to four another carbon atom is known as quaternary carbon atom.
These carbon atoms are denoted by notations as,
