Quizplus · Accepted Answer

The β-hydrogens are the hydrogens present on the carbons adjacent to the carbonyl group. In this molecule, there are two carbonyl groups, one on the first carbon and the other on the third carbon. Each carbonyl group has one β-hydrogen, making a total of two β-hydrogens in the molecule. Therefore, the correct answer is choice C: 2.
