Question -

What is the IUPAC name of the following compound?
$C H_{3} - C H_{2} - C | C H_{3} = C H - C H_{2} - C H_{3} | C H - C H_{2} - C H_{3}$

Options:

A . 3,6-Dimethyl-3-octene

B . 3,6-Dimethyl-5-octene

C . 2-Ethyl-5-methyl-2-heptene

D . None of the above

Answer: Option A
:
A

Parent chain is
$1 C H_{3} - 2 C H_{2} - 3 C | C H_{3} = 4 C H - 5 C H_{2} - C H_{3} 6 | C H - 7 C H_{2} - 8 C H_{3}$

Word root $\Rightarrow$ oct

Double bond $\Rightarrow$ suffix $\Rightarrow$ ene

Two methyl groups at $C_{3}$ and $C_{5} \Rightarrow$ 3,6-dimethyl

Therefore, 3,6-Dimethyl-3-octene
