Textbook Question
Which functional group is present in this molecule?
A.sulfhydryl
B.carboxyl
C.methyl
D.phosphate
Verified step by step guidance1
Identify the functional groups present in the molecule by examining the structure.
Look for common functional groups such as hydroxyl (-OH), carboxyl (-COOH), amino (-NH2), sulfhydryl (-SH), methyl (-CH3), and phosphate (-PO4).
Notice the presence of a carbon double-bonded to an oxygen and single-bonded to a hydroxyl group (-COOH), which is characteristic of a carboxyl group.
Confirm that the molecule contains a carboxyl group by comparing it to the structural formula of a carboxyl group.
Conclude that the functional group present in the molecule is the carboxyl group.
