Question

An organic compound A' is an essential constituent of wine and beer. Oxidation of A
yields an organic acid 'B'which is present in vinegar. Name the compounds A&B and write their structural formula. What happen when A' and 'B' react in the presence an acid catalyst? Write the chemical equation for the reaction.

Answer 1

Answer :

A : Ethanol ( CH3CH2OH)

B: Ethanoic acid(CH3COOH)

When A and B react, they form ethyl ethanoate.

Hope it helps you

Answer 2

Answer:

A is Ethanol and B is Ethanoic acid.

Explanation:

• The organic compound A is Ethyl aclcohol or Ethanol.

• Ethanol when oxidized (heated) with KMNO4 (potassim permanganate) forms Ethanoic acid which is the B organic acid.
• Structural formula of Ethyl alcohol is  C2H5OH and  that of Ethanoic acid is CH3COOH.
• When Ethanoic acid reacts with ethanol in the presence of an acid, Ethyl Ethanoate (Ester) is formed along with water.
• C2H5OH + CH3COOH ----------> CH3-COO-C2H5 + H2O.
