Homework Answers
1. Last option is correct. as carboxylic acid is most acidic in nature .
For acidity look stability of conjugate baseobtained by removal of acidic proton.
more the resonance stability of base increases also hyperconjugation is seen n case of enolate for aldehyde and ketone.
2. i is correct option as LiALH4 is a strong reducting agent that reduces aldehyde to alcohol.
3.last option is correct.It is necessary, to achieve complete conversion of aldehyde or ketone reactants to their enolate conjugate bases by treatment with a very strong base (pKa > 25) in a non-hydroxylic solvent.
