Question

Arrange the following acid derivatives in increasing ordere of their reactivity towards nucleophilic substitution reaction and support your order by suitable explanation: CH3CONH3 CH3COCL3 CH3COOCOCH CH3COOC2H5​

Answer 1

Answer:

I don't know what you are saying

Answer 2

The  correct increasing order of reactivity towards nucleophillic substitution is as follows$CH3COOC2H5 > CH3CONH3 > CH3COOCOCH > CH3COCl3$

Explanation:

• Electron-withdrawing groups will increase and electron-donating groups will decrease with the reactivity towards nucleophilic substitution.
• When more the number of electron-withdrawing groups will be present , higher will be the reactivity of the group.
• Electron donating groups includes  - R, - NH2, - NR2 etc
• Here the  electron withdrawing groups are known as  deactivating groups and electron donating groups are known as activating groups.
• In (I) electron donating ethyl group is present. So the compound will  becomes more reactive
• NH3 and chloro groups are less reactive towards nucleophilic substitution.

• order of reactivity towards nucleophilic substitution is as follows$CH3COOC2H5 > CH3CONH3 > CH3COOCOCH > CH3COCl3$
