Question

The order of reactivity of carbonyl compounds for nucleophilic addition is (A) Ar2C — O > R2C = O > ArCHO > RCHO>H2C = O (B) H2C = O > R2C = O > Ar2C = O > RCHO > ArCHO (C) H2C = O > RCHO > ArCHO > R2C = O > Ar2C = O (D) ArCHO > Ar2C = O > RCHO > R2C— O > H2C = O

With each substitution of hydrogen atom, reactivity of carbonyl compound decreases. This is due to inductive effect in case of alkyl groups and resonance in case of aromatic groups.

Q. The order of reactivity of carbonyl compounds for nucleophilic addition is

Ar₂C — O > R₂C = O > ArCHO > RCHO>H₂C = O

H₂C = O > R₂C = O > Ar₂C = O > RCHO > ArCHO

H₂C = O > RCHO > ArCHO > R₂C = O > Ar₂C = O

ArCHO > Ar₂C = O > RCHO > R₂C— O > H₂C = O

With each substitution of hydrogen atom, reactivity of carbonyl compound decreases. This is due to inductive effect in case of alkyl groups and resonance in case of aromatic groups.
