Question

Compare the acidic strength of the following compounds

• A. A>B
• B. A<B
• C. A=B
• D. None of the above

Answer 1

The correct option is B A<B

The high $e^{-}$ density on the ring system due to the presence of -OH group destabilized by hyperconjugation in the case $C{H}_3$ whereas $C{D}_3$ hyperconjugation is less. Hence B is more acidic than A.
