MCQ
Alkenes convert into alcohols by
- AHydrolysis by dil. ${H_2}S{O_4}$
- BHydration of alkene by alkaline $KMn{O_4}$
- CHydrolysis by water vapours and conc. ${H_2}S{O_4}$
- ✓Both $(b)$ and $(c)$
✓
Answer
Correct option: D.
Both $(b)$ and $(c)$
d
(d) $C{{H}_{2}}=C{{H}_{2}}+{{H}_{2}}O+[O]\xrightarrow{\text{alk}.KMn{{O}_{4}}}\underset{\text{Glycol}}{\mathop{\underset{OH\,\,\,\,}{\mathop{\underset{|\,\,\,\,\,\,\,\,}{\mathop{C{{H}_{2}}}}\,}}\,-\underset{OH\,\,\,\,}{\mathop{\underset{|\,\,\,\,\,\,\,}{\mathop{C{{H}_{2}}}}\,}}\,}}\,$
(d) $C{{H}_{2}}=C{{H}_{2}}+{{H}_{2}}O+[O]\xrightarrow{\text{alk}.KMn{{O}_{4}}}\underset{\text{Glycol}}{\mathop{\underset{OH\,\,\,\,}{\mathop{\underset{|\,\,\,\,\,\,\,\,}{\mathop{C{{H}_{2}}}}\,}}\,-\underset{OH\,\,\,\,}{\mathop{\underset{|\,\,\,\,\,\,\,}{\mathop{C{{H}_{2}}}}\,}}\,}}\,$
$\underset{\text{Ethene}}{\mathop{C{{H}_{2}}=C{{H}_{2}}}}\,+{{H}_{2}}O\xrightarrow{\text{Conc}\text{.}{{H}_{2}}S{{O}_{4}}}\underset{\text{Ethanol}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-OH}}\,$
