Question
The two functional groups in carboxylic acids are __________ & ___________
Correct Answer
Option A is the correct answer.
Detailed Explanation
This question seems to be describing an amino acid, not a carboxylic acid. A carboxylic acid has the functional group -COOH (carboxyl group). An amino acid has both an amino group (-NH2) and a carboxyl group (-COOH). Given the options, only A lists -NH2 and -COOH, which are the functional groups of an amino acid.
Hint
Which two functional groups characterize an amino acid?
