MCQ
The reaction, ${H_2}C\mathop { = C{H_2}}\limits_{{\text{Ethylene}}} + \mathop {{H_2}O}\limits_{{\text{water}}} \mathop {\xrightarrow{{{H_3}P{O_4}}}}\limits_{300\,^o C/60\,atm..} \mathop {{C_2}{H_5}OH}\limits_{{\text{Ethyl alcohol}}} $ is called :
  • ✓
    Hydration
  • B
    Sublimation
  • C
    Dehydration
  • D
    Substitution
✓

Answer

Correct option: A.
Hydration
a
(a) Alkenes react with water in the presence of acid and form alcohols. This reaction is called as hydration.
$\mathop {H - \mathop {\mathop C\limits_| }\limits_H = \mathop {\mathop C\limits_| }\limits_H - H + {H_2}O}\limits_{{\text{Ethylene}}} \mathop {\xrightarrow{{{H_3}P{O_4}}}}\limits_{300\,^o C/60\,atm} \mathop {H - \mathop {\mathop C\limits_|^| }\limits_H^H - \mathop {\mathop C\limits_|^| }\limits_H^H - H}\limits_{{\text{Ethyl alcohol}}} $
