Question

Match the name of acid from List-I with the source from which it is derived.

• A. \[ a-(i),\quad b-(ii),\quad c-(iii) \]
• B. \[ a-(ii),\quad b-(i),\quad c-(iii) \]
• C. \[ a-(iii),\quad b-(ii),\quad c-(i) \]
• D. \[ a-(iii),\quad b-(i),\quad c-(ii) \]

Hint:

Remember these common natural sources: \[ \text{Formic Acid} \rightarrow \text{Ant} \] \[ \text{Acetic Acid} \rightarrow \text{Vinegar} \] \[ \text{Butyric Acid} \rightarrow \text{Butter} \] These associations are frequently asked in biomolecules and organic chemistry questions.

Answer 1

The Correct Option is D

Step 1: Match Formic Acid.
Formic acid derives its name from the Latin word formica, meaning ant. It is naturally present in ant stings and is responsible for the irritating sensation caused by ant bites. Therefore, \[ \text{Formic Acid} \rightarrow \text{Ant} \] \[ a \rightarrow (iii) \]

Step 2: Match Acetic Acid.
Acetic acid is the principal acidic component of vinegar. Vinegar is a dilute aqueous solution of acetic acid produced by the oxidation of ethanol. Therefore, \[ \text{Acetic Acid} \rightarrow \text{Vinegar} \] \[ b \rightarrow (i) \]

Step 3: Match Butyric Acid.
Butyric acid is found in rancid butter and is responsible for its characteristic unpleasant odor. The name butyric is derived from the Greek word boutyron, meaning butter. Therefore, \[ \text{Butyric Acid} \rightarrow \text{Butter} \] \[ c \rightarrow (ii) \]

Step 4: Write the final matching.
Thus, \[ a-(iii),\quad b-(i),\quad c-(ii) \]

Step 5: Final conclusion.
Hence, the correct matching is \[ \boxed{ a-(iii),\quad b-(i),\quad c-(ii) } \] Therefore, option (4) is correct.
