If diethyl amine is treated separately with the following derivatives ...
To determine the order of reactivity when diethyl amine is treated separately with the given derivatives of isobutyric acid, we need to consider the nature of each derivative and how it reacts with amines.
I. Isobutyronitrile (2-methylpropanenitrile):
Nitriles are generally less reactive than acyl chlorides and anhydrides. They undergo nucleophilic addition reactions with amines to form imines. The reaction is relatively slow and requires the presence of a catalyst.
II. Isobutyryl chloride (2-methylpropanoyl chloride):
Acyl chlorides are highly reactive towards amines and readily undergo nucleophilic acyl substitution reactions. The reaction between an acyl chloride and an amine is typically rapid and does not require a catalyst.
III. Ethyl isobutyrate:
Esters are less reactive than acyl chlorides and anhydrides. They undergo nucleophilic acyl substitution reactions with amines, but the reaction is slower compared to acyl chlorides. The reaction may require heating or the presence of a catalyst.
IV. Isobutyric anhydride (2-methylpropanoic anhydride):
Anhydrides are highly reactive towards amines and readily undergo nucleophilic acyl substitution reactions. The reaction between an anhydride and an amine is typically rapid and does not require a catalyst.
Based on the reactivity trends discussed above, the expected order of reactivity is as follows:
II. Isobutyryl chloride (2-methylpropanoyl chloride) - highest reactivity
IV. Isobutyric anhydride (2-methylpropanoic anhydride)
III. Ethyl isobutyrate
I. Isobutyronitrile (2-methylpropanenitrile) - lowest reactivity
This order is determined by the nature of the functional groups present in each derivative. Acyl chlorides and anhydrides are highly reactive due to the presence of a highly polarized C=O bond and the ability to form a stable leaving group. Nitriles are less reactive due to the presence of a less polarized C≡N bond. Esters are even less reactive due to the presence of a less polarized C=O bond and the absence of a good leaving group.
