c

Answer to Question 2



Answer to Question 3



Answer to Question 4



Answer to Question 5



Answer to Question 6



Answer to Question 7



Answer to Question 8

ANS: CH3CH2CH2NH2

Strongest base because it is the only aliphatic amine.



Weakest based because it is an amide not an amine and is not considered basic.

Answer to Question 9



Answer to Question 10

Dissolve the reaction mixture containing the ketone and amine in ether and extract with aqueous HCl. The basic amine will dissolve in the aqueous layer as its hydrochloric salt. The neutral ketone will remain in the ether layer. Separate the two layers and neutralize the aqueous layer with NaOH. Extract the neutralized layer with ether. The purified amine will dissolve in the ether.

Answer to Question 11

c

Answer to Question 12

a
