Mark the correct order of increasing reactivity:
Which of the following compounds will be most easily hydrolysed?
Acid halide is most easily hydrolysed as halide is a strong leaving group and weak conjugate base. Weaker the basic character of leaving group more is the reactivity of acid derivative.
Mark the correct order of increasing reactivity:
Arrange the following compounds in the increasing order of their property as indicated: Acetaldehyde, acetone, di-tert-butyl ketone, methyl tert- butyl ketone (reactivity towards HCN).
The reactivities of acid halides (I), anhydrides (II), esters (III) and amides (IV) with nucleophilic reagents follow the order :
In which option first one is more reactive than second in each pair towards $$S_{N}2$$ reaction ?
Which of the most reactive acid derivative?
Which among the following ester is most reactive towards nucleophilic attack?
Fill in the blanks: (S) Acetic anhydride is ..... reactive than acetyl chloride.
Answer the following with reasoning:- (v) How the order of reactivity of the acid derivatives is related to the base strength of the leaving group?
Answer the following with reasoning:- (ix) Why a ketone is not isolated from the reaction of an ester on equivalent of RMgX?
