Incorrect order of the following with respect to nucleophillic addition reaction of carbonyl compound is
A
Reactivity `HCHOgtCH_(3)CHOgtCH_(3)COCH_(3)`
B
Reactivity `PHCHOgtHCHO`
C
Electrophilicity of carbonyl carbon `HCHOgtCH_(3)CHOgtCH_(3)COCH_(3)`
D
Electrophicityy of carbonyl carbon: `HCHOgtPhCHO`
Text Solution
Verified by Experts
The correct Answer is:
B
Polarity of carbonyl group is reduced in `Ph-CHO` due to resoance. Hence the respective carbonyl carbon is less electrophilic that that propanal and therefore less reactive. Hence reactivity order `(H_(3)"CC"H_(2)CH)gtPhCHO)`
