2. Determine the name based on its functional group and carbon chain length.

Relevant Concepts

1. The given compound contains:
   • A linear chain of 3 carbon atoms.
   • An aldehyde functional group (-CHO) at the end.

Analysis and Detail

1. Count the carbon atoms:
   • CH₃ (1 carbon) + CH₂ (1 carbon) + CHO (1 carbon) = 3 carbon atoms total.
2. The presence of the aldehyde functional group indicates that it is not a ketone or an alcohol.

Verify and Summarize

• The compound contains three carbon atoms with an aldehyde functional group, which is characteristic of propanal.

Final Answer

The name of the compound CH₃ – CH₂ – CHO is A) Propanal.
