Quizplus · Accepted Answer

The compound is a two-carbon aldehyde with the formula CH3CHO. The IUPAC name for this compound is ethanal. Option A (methyl aldehyde) is incorrect because there is no methyl group present in the compound. Option B (1-ethanaldehyde) is redundant, as "ethanal" already indicates the aldehyde functional group at the first carbon. Option C (1-ethanone) is incorrect because the compound does not have a ketone functional group. Option E (methanal) is incorrect because "meth-" indicates a one-carbon compound, whereas ethanal has two carbons.
