Solution

$a)$ Isopentyl : $H_{3} C - C H | C H_{3} - C H_{2} - C H_{2}$ $⟹ 3 - m e t h y l b u t y l .$
$b)$ t-pentyl : $H_{3} C - C H_{2} - C H_{3} | C | C H_{3} -$ $⟹ 1, 1 - d i m e t h y l p r o p y l .$

$c)$ Isohexil : $H_{3} C - C H | C H_{3} - C H_{2} - C H_{2} -$ $⟹ 4 - m y t h y l p e n t y l .$

$d)$ Neohexil : $H_{3} C - C H_{3} | C | C H_{3} - C H_{2} - C H_{2} -$ $⟹ 3, 3 - d i m e t h y l b u t y l .$
