Solution

Break Down the Problem

  1. Identify the structure of the compound represented by the formula CH₃—CH₂—CHO.
  2. Determine the functional group and the longest carbon chain to deduce the name.

Relevant Concepts

  1. The formula CH₃—CH₂—CHO indicates that the compound contains three carbon atoms in total.
  2. It has an aldehyde functional group (–CHO) because the carbonyl group (C=O) is at the end of the carbon chain.

Analysis and Detail

  1. The longest carbon chain consists of three carbon atoms.
  2. Since the functional group (aldehyde) is present, we can conclude that the compound is part of the aldehyde family.
  3. Thus, we can use the naming convention for aldehydes; the base name is derived from the number of carbon atoms in the chain.

Naming

  • For three carbons, the base name is "prop."
  • Since it is an aldehyde, we add "anal" to the base name, resulting in "propanal."

Verify and Summarize

We correctly identified the compound's structure, the functional group, and the longest carbon chain.

Final Answer

The name of the compound CH₃—CH₂—CHO is (a) Propanal.
