Question

Aldehyde and ketone undergo nucleophilic addition reaction because of polarity between `gtC=O` group . The reactivity of carbonyl groups toward nucleophile depends upon the nature of inductive effect of froup present at carbonyl carbon.
Nucleophilic addition reaction over carbonyl compound is shown by :
A. `HCN+ dil .NaOH `
B. `NaHSO_(3)`
C. `CH_(3)OH+HCl`
D. all of these

Answer 1

Correct Answer - D
`A=F CH_(2)CHO,` electron withdrawing group increases group increases electrophilicity of carbon increasing reate of nucleophilic addition reaction while conjugation or electron donating group decreases electrophilicity.
`C_(6)H_(5)-overset(O)overset(||)(C)-C_(6)H_(5)`
