Question

The stability order of $π$ - bond in following alkenes in the increasing order is:
$C H_{3} - C H = C H_{2} (I)$

$C H_{3} - C | C H_{3} = C | C H_{3} - C H_{3} (I I)$

$C H_{3} - C | C H_{3} = C H_{2} (I I I)$

$C H_{3} - C | C H_{3} = C H - C H_{3} (I V)$

I < III < IV < II

Solution

The correct option is A I < III < IV < II
Stability of alkene $\propto$ Number of $α$ -H atoms.
Structure (I) has 3 $α$ -H, (II) has 12 $α$ -H, (III) has 6 $α$ -H, and (IV) has 9 $α$ -H. Therefore, the stability order of $π$ -bond in the alkenes is:
I < III < IV < II
