MCQ
Ethanol is prepared industrially by
- AHydration of ethylene
- BFermentation of sugars
- ✓Both the above
- DNone of these
✓
Answer
Correct option: C.
Both the above
c
(c) Hydration of alkenes
(c) Hydration of alkenes
$C{H_2} = C{H_2} + \mathop {{\text{ }}H}\limits^ + S{\mathop O\limits^ - _4} \to C{H_3} - C{H_2} - HS{O_4}$
$C{H_3} - C{H_2}HS{O_4}\mathop {\xrightarrow{{{H_2}O}}}\limits_{Boil} C{H_3} - C{H_2} - OH + {H_2}S{O_4}$
Fermentation of sugars:
${C_{12}}{H_{22}}{O_{11}} + {H_2}O\xrightarrow{{{\text{Invertase}}}}\mathop {{C_6}{H_{12}}{O_6}}\limits_{{\text{Glucose}}} + \mathop {{C_6}{H_{12}}{O_6}}\limits_{{\text{Fructose}}} $
$\mathop {{C_6}{H_{12}}{O_6}}\limits_{{\text{Glucose}}\,\,{\text{or}}\,{\text{Fructose}}} \xrightarrow{{{\text{Zymase}}}}\,2{C_2}{H_5}OH + 2C{O_2}$
