(a)
Interpretation:
The structural formulaof 2,3-dimethylpentane should be drawn.
Concept Introduction:
Alkanes can be classified as-
- Straight-chain alkanes
- Branched-chain alkanes
(a)
Answer to Problem 17A
Explanation of Solution
The given name of branched alkane is 2,3-dimethylpentane where pentane represents the parent carbon chain. For drawing the structure, firstly principal chain of five carbon atom is drawn and numbering is done. Then at position 2 and 3, methyl group is attached. After this, valency of each carbon is completed.
The structure of 2,3-dimethylpentane is:
(b)
Interpretation:
The structural formula of 2,4-dimethylpentane should be drawn.
Concept Introduction:
Alkanes are the saturated hydrocarbons which contain only C-H and C-C single bonds. The general formula of alkane is CnH2n+2. The simplest alkane among all alkanes is methane CH4.
Alkanes can be classified as-
- Straight-chain alkanes
- Branched-chain alkanes

Answer to Problem 17A
Explanation of Solution
The given name of branched alkane is 2,4-dimethylpentane where pentane represents the parent carbon chain. For drawing the structure, firstly principal chain of five carbon atom is drawn and numbering is done. Then at position 2 and 4, methyl group is attached. After this, valency of each carbon is completed.
The structural formula of 2,4-dimethylpentane is:
(c)
Interpretation:
The structural formula of 2,2-dimethylpentane should be drawn.

Explanation of Solution
The given name of branched alkane is 2,2-dimethylpentane where pentane represents the parent carbon chain. For drawing the structure, firstly principal chain of five carbon atom is drawn and numbering is done. Then at position 2, two methyl groups are attached. After this, valency of each carbon is completed.
The structural formula of 2,2-dimethylpentane is:
(d)
Interpretation:
The structural formula of 3,3-dimethylpentane should be drawn.
