(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
(b)
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.

- Please correct answer and don't use hand rating and don't use Ai solutionarrow_forward1. For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
