Question

Quizplus · Accepted Answer

2-methylpentanal can undergo keto-enol tautomerism because it has a hydrogen atom adjacent to the carbonyl group, allowing for the necessary proton transfer. 2,2-dimethylbutanal cannot undergo this tautomerism because it lacks such a hydrogen atom adjacent to the carbonyl group.
