Answer 2

Differentiation of ethanol and ethanoic acid under the give heads.

• Ethanol and ethanoic acid are compounds which have different functional groups.

• Ethanol is alcohol as it has '-OH' group in its structure, whereas ethanoic acid is a carboxylic acid due to the presence of '-COOH' in its structure.

• The formula of ethanol and ethanoic acid is $C_2H_5OH$ and $CH_3COOH$respectively.

(a) Tabular form of differentiation is given in the attachment.

(b) Dehydration of ethanol

• The process of removal of water molecule from ethanol is called as dehydration of ethanol.
• This mechanism converts ethanol to ethylene. The chemical equation involved in the reaction is as follows:

$CH_3-CH_2-OH+Al_2O_3\rightarrow CH_2=CH_2+H_2O$
