Solution

The correct option is D $C H_{3} - C H_{2} - C H_{2} - C H_{2} - C H_{3}$ and $C H_{3} - C H (C H_{3}) - C H_{2} - C H_{3}$
$C H_{3} - C H (C H_{3}) - C H_{2} - C H_{3}$ is a branched chain compound and $C H_{3} - C H_{2} - C H_{2} - C H_{2} - C H_{3}$ is a straight chain compound with same molecular formula. Thus they are chain isomers .
