Question

Quizplus · Accepted Answer

The systematic name of vanillan is 4-hydroxy-3-methoxybenzaldehyde. This is because it contains a hydroxyl group (-OH) and a methoxy group (-OCH3) on the benzene ring, as well as an aldehyde group (-CHO) on the carbon next to the benzene ring. The other answer choices contain different combinations of functional groups or they have the functional groups in different positions on the benzene ring, making them incorrect systematic names for vanillan.
