Options:

A) $ (C_6H_{10}O_5)n $

B) $ C_2H_5OH $

C) $ C_6H_{12}O_6 $

D) $ CH_3OH $

Show Answer

Answer:

Correct Answer: B

Solution:

$ C_{12}H_{22}O_{11}+H_2O\underset{Invertase}{\mathop{\xrightarrow{Yeast}}},\underset{\text{(Glucose)}}{\mathop{C_6H_{12}O_6}},+\underset{(Fructose)}{\mathop{C_6H_{12}O_6}}, $ $ C_6H_{12}O_6\underset{Zymase}{\mathop{\xrightarrow{Yeast}}},\underset{\text{(Ethyl alcohol)}}{\mathop{2C_2H_5OH}},+2CO_2 $
