MCQ
The reaction of propene with $HOCl (Cl_2 + H_2O)$ proceeds through the intermediate :
- A$CH_3 -CH(OH)-CH_2^+$
- B$CH_3 -CHCl-CH_2^+$
- C$CH_3 -CH^+ -CH_2 -OH$
- ✓$CH_3 -CH^+ -CH_2 -Cl$
✓
Answer
Correct option: D.
$CH_3 -CH^+ -CH_2 -Cl$
d
$C{{H}_{3}}-CH=C{{H}_{2}}\xrightarrow[(electrophilic\,addition)]{\overset{\delta -}{\mathop{HO}}\,-\overset{\delta +}{\mathop{Cl}}\,}$ $\underset{(\operatorname{int}ermediate)}{\mathop{C{{H}_{3}}-\overset{+}{\mathop{C}}\,H-C{{H}_{2}}-Cl}}\,$ $\xrightarrow{O{{H}^{-}}}C{{H}_{3}}-CH(OH)-C{{H}_{2}}-Cl$
$C{{H}_{3}}-CH=C{{H}_{2}}\xrightarrow[(electrophilic\,addition)]{\overset{\delta -}{\mathop{HO}}\,-\overset{\delta +}{\mathop{Cl}}\,}$ $\underset{(\operatorname{int}ermediate)}{\mathop{C{{H}_{3}}-\overset{+}{\mathop{C}}\,H-C{{H}_{2}}-Cl}}\,$ $\xrightarrow{O{{H}^{-}}}C{{H}_{3}}-CH(OH)-C{{H}_{2}}-Cl$
