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 SN2 displacements do not occur at tertiary alkyl halides, the Grignard reagent carboxylation is the best method for carrying out this conversion.

Answer to Question 6

a)


b)


Answer to Question 7



Answer to Question 8



Answer to Question 9

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
