Question: 140
5. Intermediates in the Strecker synthesis include all of the following nitrogen-containing functional groups EXCEPT a(n):
- A. nitrile.
- B. imine.
- C. amide.
- D. amine.
Correct Answer: C
Explanation:
During the Strecker synthesis, ammonia attacks a carbonyl, forming an imine, choice (B). This imine is attacked by cyanide, forming an amine, choice (D), and a nitrile, choice (A). Amide bonds are formed between amino acids, but do not appear during the Strecker synthesis.
