This reaction between an enamine and an alkyl halide involves the following steps: 1. The enamine acts as a nucleophile in an SN2 reaction, displacing bromide ion to form addition product 1; 2. Deprotonation yields carbanion 2; 3. Ring closure leads to the final product. Write the mechanism out on a sheet of paper, and then draw the structure of carbanion 2.

This question is about electrolysis. metal spoons can be coated with silver. this is called electroplating. suggest one reason why spoons are electroplated?
