Answer & Solution
Correct Answer
(B) D \(>\) C \(>\) B \(>\) A
Step-by-step Solution
Detailed explanation
(b) Key Idea Acidic strength increases with presence of \(E W G\) (i.e. groups show-I effect) and decreases with the presence of EDG (i.e. groups show \(+I\) or hyperconjugation effect). More be the number and more close be the EWG to the \(-\mathrm{COOH}\) group, more is the…
