alleryWhat is the IUPAC name of the compound CH3-CH2-OH?
AEthanol
BEthanoic acid
CMethanol
DEthanal
Answer & Solution
Correct answer: A. Ethanol
1. The carbon chain has two carbons, so the parent is ethane.
2. The functional group -OH takes the suffix 'ol'.
3. Replace the final 'e' of ethane with 'ol' to get ethanol.
4. Rule out D: ethanal would need a -CHO (aldehyde) group, not -OH.
