Pent- $2$ -ene

$3, 4$ -Dimethylhept- $3$ -ene

$2$ -Ethylbut- $1$ -ene

$1$ -Phenylbut- $1$ -ene

$H_{3} C - C H_{2} - Pentan - 2 - one C H_{2} - C ∣ H_{3} C = O + O = Butan -2- one C ∣ C H_{3} - C H_{2} - C H_{3}$

Can be given by $H_{3} C - H_{2} C - H_{2} C - C ∣ H_{3} C = C ∣ C H_{3} - C H_{2} - C H_{3}$
