Q. $n$-pentane, iso-pentane, and $neo$ – pentane are examples for isomers of the type
A) Geometrical
B) Optical
C) Chain
D) Positional
Explanation
(c)
The compounds which differ in the nature of carbon chain are called chain isomers, e.g.,
$CH_{3} - CH_{2} - CH_{2} - CH_{2} - CH_{3}$
n-pentane
$\ \ \ \ \ \ \ \ \ \ \ \ CH_{3}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \$
|
$CH_{3} - CH - CH_{2} - CH_{3}$
iso-pentane
$CH_{3}$
|
$H_{3}C - C - CH_{3}$
|
$\ \ \ \ \ \ \ \ \ \ \ \ \ CH_{3}$
neo-pentane
