Solution

The correct option is C
5-Methyl-2-hexene

$\to$ Parent chain??

6 carbons $\Rightarrow$ Word root = Hex

Double bond $\Rightarrow$ Primary suffix = ene

Give numbering so that double bond gets the least number.

$C 6 H_{3} - C H_{3} | C H 5 - C 4 H_{2} - C 3 H = C 2 H - C 1 H_{3}$

$\to$ a methyl $(- C H_{3}$ ) group on $C_{5}$

Therefore,

5-methyl-2-hexene
