Answer to Question 1



Answer to Question 2

c

Answer to Question 3



Answer to Question 4

Amine protons interfere with the formation of Grignard reagents, so nitrile hydrolysis is the best method for carrying out this conversion.

Answer to Question 5

Since S_N2 displacements do not occur at tertiary alkyl halides, the Grignard reagent carboxylation is the best method for carrying out this conversion.
