Question

An organic compound A of molecular formula C2H6O is a constituent of wine and beer. This compound on heating with alkaline potassium permanganate forms another organic compound B which turns blue litmus to red. Identify the compounds A and B.

Answer 1

Compound A is Ethyl Alcohol or Ethanol

Explanation:

• The organic compound which is a constituent of wine and beer is Ethyl alcohol $C_2H_5OH$.

When Ethyl alcohol treated with alkaline $KMnO_4$ it produces Ethanoic acid (Acetic acid-$CH_3COOH$), this acetic acid turns blue litmus to red.

$C_2H_5OH$+ alkaline.$KMnO_4$→ $CH_3COOH$

Therefore A =  $C_2H_5OH$

B = $CH_3COOH$
