Questions & Step-by-Step Solutions
What is the IUPAC name of the compound with the formula C5H10O?
Step 1: Identify the molecular formula C5H10O. This indicates that the compound contains 5 carbon atoms, 10 hydrogen atoms, and 1 oxygen atom.
Step 2: Determine the functional group. The presence of the oxygen suggests it could be an alcohol, ether, or carbonyl compound (ketone or aldehyde).
Step 3: Check the degree of saturation. The formula CnH2nO indicates that it is likely a ketone because it fits the formula for a ketone (C=O) with no additional hydrogens that would indicate an alcohol.
Step 4: Identify the longest carbon chain. In this case, the longest chain has 5 carbon atoms.
Step 5: Determine the position of the carbonyl group (C=O). For a ketone, the carbonyl group is located between two carbon atoms, which in this case is at the second carbon of the chain.
Step 6: Combine the information to name the compound. The longest chain is pentane (5 carbons), and since the carbonyl group is on the second carbon, the name is 2-Pentanone.
