The given structures, CH_3 | _3-CH-CH_3 and CH_3 CH_2 CH_2 CH_3 a… - Vidyadip

MCQ

The given structures, $\ \ \ \ \ \ \ \ \ \ \ \ \text{CH}_3\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\\text{CH}_3-\text{CH}-\text{CH}_3$ and $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{CH}_3$ are :

A
Conformational isomers.
✓
Chain isomers.
C
Position isomers.
D
Functional isomers.

✓

Answer

Correct option: B.

Chain isomers.

$\ \ \ \ \ \ \ \ \ \ \ \ \text{CH}_3\\ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\\text{CH}_3-\text{CH}-\text{CH}_3,\ \text{CH}_3-\text{CH}_2-\text{CH}_2-\text{CH}_3\\ \ \ \ \ _{2-\text{methylpropane}} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ _{\text{n-butane}}$
Molecular formula $\rightarrow$ Same
Chain of $C-$ atom $\rightarrow$ Different
Hence, these are chain isomers.
