B) Ethene

hope it will help you

Answer 2

Organic compound A is identified as Ethyl alcohol.

Organic compound B is identified as Acetic acid.

Explanation:

The organic compound A of molecular formula $C_2H_6O$, that is an ingredient of wine and beer signifies $C_2H_5OH$ ethyl alcohol.

When ethyl alcohol-treated among alkaline Potassium permanganate $KMnO_4$ provides ethanoic acid (acetic acid-$CH_3COOH$) which is the organic compound B. This acetic acid changes blue litmus to red.

$C_2H_5OH + alkaline.KMnO_4 -> CH_3COOH$

Therefore

Organic compound A is identified as ethyl alcohol $C_2H_5OH$

Organic compound B is identified as acetic acid $CH_3COOH$
