Question

Among the following the strongest nucleophile is?

• A. \( \text{C}_2\text{H}_5\text{SH} \)
• B. \( \text{CH}_3\text{COO}^- \)
• C. \( \text{CH}_3\text{NH}_2 \)
• D. \( \text{NCH}_3 \)

Hint:

Nucleophilicity increases with the electron density of the nucleophile and decreases with its basicity.

Answer 1

The Correct Option is A

Sulfide ions (\( \text{SH}^- \)) are typically stronger nucleophiles than amines or carboxylates due to their higher electron density and lower basicity.
