REACTIVITY OF AROMATIC & ALIPHATIC ALDEHYDE & KETONE

STATEMENT -1: Aldehydes are more Reactive then corresponding ketone for Nucleophillic reactions STATEMENT -2: Due to electron density at functional group carbon which is higher in ketone than in Aldehyde.

Reactivity of PhMgBr with the following in the decreasing order is : (i) Alcohol (ii) Aldehyde (iii) Ketone (iv) Ester.

A : Aromatic aldehydes are less reactive than aliphatic aldehyde towards nucleophilic substitution reaction. R : In case of aromatic aldehyde,+R effect of phenyl ring is present.

Assertion:-Aliphatic aldehyde can be diffrentiate from aromatic aldehyde by Fehling solution. Reason:- This is because aliphatic aldehyde reduce fehling solution but aromatic aldehyde donot.
