The correct order of acidic nature of the following alkynes is I. C ₂ H ₂ II. ( CH ₃ )₂ C ₂ III. ( CH ₃ ) C ₂ H
Options
- AI < III < II
- BII < III < I
- CIII < II < I
- DII < I < III
Correct answer
B. II < III < I
Step-by-step solution
Due to the (+ R ) effect of methyl group the stability of conjugate bases decreases from (III) to (II): Correct order of acidity : (II) < (III) < (I)
