The reaction of propene with $\mathrm{HOCl}\left(\mathrm{Cl}_2+\mathrm{H}_2 \mathrm{O}\right)$ proceeds through intermediate :
  • A
    $\ \ \ \ \ \ \ \ \ \ \ \ \oplus\\\text{CH}_3-\text{C}\text{H}-\text{CH}_2\text{OH}$
  • ✓
    $\ \ \ \ \ \ \ \ \ \ \ \ \oplus\\\text{CH}_3-\text{C}\text{H}-\text{CH}_2-\text{Cl}$
  • C
    $ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \oplus\\ \text{CH}_3-\text{CH(OH)}\text{CH}_2$
  • D
    $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \oplus\\ \text{CH}_3\text{CHCl }\text{CH}_2$
✓

Answer

Correct option: B.
$\ \ \ \ \ \ \ \ \ \ \ \ \oplus\\\text{CH}_3-\text{C}\text{H}-\text{CH}_2-\text{Cl}$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ominus\\\text{HOCl}\rightarrow\text{OCH}+\text{Cl}^+$
