Question

Which of the following substances can be used as a raw material for obtaining alcohol?
A.Potatoes
B.Molasses
C.Maize
D.All of the above

Answer 1

We have to know that alcohol is a functional group having hydroxyl group, $\left( { - OH} \right)$ as a functional group. And these are mainly produced by the fermentation process by using some sources of sugar, grains and fruits etc. And the alcohol is mainly divided into four types and that is, ethyl alcohol, denatured alcohol, isopropyl alcohol and rubbing alcohol. And this is used in liquor, beer, wine etc.

Complete answer:
We must have to know that vodka is a type of alcohol which can be produced from potatoes by fermentation process. Because it contains starch. But from the given options, potato is not the only one row material used for the preparation of alcohol. Hence, option (A) is incorrect.
The molasses is a viscous product which is prepared from sugarcane. And the molasses is widely used for the preparation of alcohol due to the presence of a rich amount of nutrients. Thus it is a very effective raw material for the preparation of alcohol, mainly ethanol and it is prepared by anaerobic fermentation. But from the given option, this is not the only raw material which is used for the preparation of alcohol. Hence, the option (B) is incorrect.
The maize is also known as corn. It is widely used for the preparation of alcohol. Because it contains a large amount of starch and cellulosic material for the preparation of bioethanol. And other options can also be used for the preparation of alcohol. Hence, option (C) is incorrect.
Among the given options, potato, molasses, and maize can be used as a raw material for the preparation of alcohol.

Hence, the option (D) is correct.

Note:
Starch is the main content for the preparation of alcohol. And potatoes, molasses, maize, fruits, honey, sugarcane, etc can be used as raw material for the preparation of alcohol. And the alcohol is prepared by fermentation. The wine is an alcohol which is prepared from grapes and the beer is prepared from other types of grain. For each alcohol, the row material should be different.
