All of the following are examples of functional groups in biology except:
A
-CH3
B
-COOH
C
-H2O
D
-NH2
E
-OH
Verified step by step guidance1
Identify the functional groups listed in the problem: -CH3 (methyl group), -COOH (carboxyl group), -NH2 (amino group), and -OH (hydroxyl group).
Understand that functional groups are specific groups of atoms within molecules that have characteristic properties and reactivity.
Recognize that -CH3, -COOH, -NH2, and -OH are all functional groups commonly found in biological molecules.
Consider the option -H2O, which is a molecule of water and not a functional group. Functional groups are typically part of larger molecules, not standalone molecules.
Conclude that -H2O is the correct answer as it is not a functional group, unlike the other options provided.
