Question

Draw curved arrows to show the flow of electrons responsible for the conversion of the following reactants into products.

Short answer

a) Here oxygen lone pair shifts to the carbon oxygen bond and form double bond then cleavage of OCH₃and C bond takes place. CH₃O^- ion will release.

b) In this nucleophilic (nucleus loving) attack takes place. Nitrogen lone pair attacks on hydrogen and attract hydrogen towards itself and form NH₃ and carboanion will form.

c) In this nucleophilic (nucleus loving) attack takes place. Oxygen lone pair attacks on carbon and form bond with it and Br^-releases.

Step-by-step solution

Step 1: How the reaction proceed

a) Here oxygen lone pair shifts to the carbon oxygen bond and form double bond then cleavage of OCH₃and C bond takes place. CH₃O^- ion will release.

b) In this nucleophilic (nucleus loving) attack takes place. Nitrogen lone pair attacks on hydrogen and attract hydrogen towards itself and form NH₃ and carboanion will form.

c) In this nucleophilic (nucleus loving) attack takes place. Oxygen lone pair attacks on carbon and form bond with it and Br^-releases.

Final answer

So the reaction proceed like this-
