MCQ
Strength of acidity is in order:
- A$\ce{II>I}$
- ✓$\ce{I>II}$
- C$\ce{I=II}$
- DCan not be determined
✓
Answer
Correct option: B.
$\ce{I>II}$
As we know that the strength of acidity inversely depends upon the $+I$ effect.
Thus, due to $+I$ effect of methyl group $\left(-\mathrm{CH}_3\right), I$ is more acidic than $II.$
Hence the correct order of strength of acidity is $-I>II.$
Thus, due to $+I$ effect of methyl group $\left(-\mathrm{CH}_3\right), I$ is more acidic than $II.$
Hence the correct order of strength of acidity is $-I>II.$
