Answer 2

Preparation:

Ethanol is prepared on large scale from ethene by the addition of water vapour to it in the presence of catalysts.

☘︎Tungsten oxide at high pressure and temperature.

$ch_{2} = ch_{2} + h_{2} o = > ch_{3} ch_{2}oh$

★Grain such as corn ,wheat ,barley are common sources for ethanol.

★Therefore,it is also called grain alcohol

$cooking \: grain + sprouted \: barley \: = > glucose = > ethanol + co_{2}$

☀︎The process of conversion of starches and sugars is called fermentation process
