JEE PYQ: General Organic Chemistry Question 9
Question 9 - 2021 (18 Mar Shift 2)
Given below are two statements:
Statement I: $\text{C}_2\text{H}_5\text{OH}$ and AgCN both can generate nucleophile.
Statement II: KCN and AgCN both will generate nitrile nucleophile with all reaction conditions.
(1) Statement I is true but statement II is false
(2) Both statement I and statement II are true
(3) Statement I is false but statement II is true
(4) Both statement I and statement II are false
Show Answer
Answer: (1)
Solution
$\text{C}_2\text{H}_5\text{OH}$ can generate $\text{C}_2\text{H}_5\text{O}^-$ nucleophile and AgCN generates $\text{CN}^-$ nucleophile. However, KCN gives $\text{CN}^-$ (nitrile) while AgCN gives $\text{NC}^-$ (isocyanide), so Statement II is false.
