MCQ
Rank in the order of increasing acidic strength:
- AA < B < C
- BA < C < B
- CB < A < C
- DB < C < A
Explanation:
The greater I effect is favorable or greater acidic strength. The −I effect of aldehyde group is greater than the ester group. Due to this C will be most acidic.
In A and B, B will be less acidic as it has −I effect sort of localized due to ester group being on a single carbon. In A it is more delocalized is not effective on more by adjacent carbons.
Hence, the required order is- B < A < C.
