Questions & Step-by-Step Solutions
Which of the following is the correct IUPAC name for CH3CHO?
Step 1: Identify the molecular formula CH3CHO. This shows that the compound contains carbon (C), hydrogen (H), and oxygen (O).
Step 2: Count the number of carbon atoms in the formula. There are 2 carbon atoms (one in CH3 and one in CHO).
Step 3: Determine the functional group present. The CHO part indicates that this compound is an aldehyde because it has a carbonyl group (C=O) at the end of the carbon chain.
Step 4: Name the longest carbon chain. The longest chain has 2 carbon atoms, which corresponds to the prefix 'eth-' in IUPAC nomenclature.
Step 5: Since it is an aldehyde, we add the suffix '-al' to the name. Therefore, we combine 'eth-' and '-al' to get 'ethanal'.
Step 6: Conclude that the correct IUPAC name for CH3CHO is Ethanal.
