Which of the Following Functional Groups are Not Commonly Seen

Question

Which of the following functional groups are not commonly seen in biomolecules?
A) Alkyl halides
B) Amides
C) Carboxylic acids
D) Ethers
E) Phosphate esters

Accepted Answer

Alkyl halides are not commonly seen in biomolecules as they are relatively unreactive and do not participate in many of the chemical reactions that biomolecules undergo. Biomolecules typically contain functional groups such as amides, carboxylic acids, ethers, and phosphate esters that are more reactive and play important roles in biochemical processes.
