Questions & Step-by-Step Solutions
What is the IUPAC name for the compound with the formula C5H10O2 that contains an ester functional group?
Step 1: Identify the molecular formula C5H10O2. This indicates that the compound contains 5 carbon atoms, 10 hydrogen atoms, and 2 oxygen atoms.
Step 2: Recognize that the compound is an ester because it contains a carbonyl group (C=O) and an alkoxy group (R-O).
Step 3: Determine the structure of the ester. Esters are formed from an alcohol and a carboxylic acid.
Step 4: Identify the carboxylic acid that can be derived from the compound. The longest carbon chain with a carboxylic acid functional group is butanoic acid (4 carbon atoms).
Step 5: Identify the alcohol used to form the ester. The remaining carbon (1 carbon) comes from ethanol (ethyl alcohol).
Step 6: Combine the names of the alcohol and the carboxylic acid. The alcohol (ethanol) gives the 'ethyl' part, and the carboxylic acid (butanoic acid) gives the 'butanoate' part.
Step 7: Put it all together. The IUPAC name for the compound C5H10O2 is ethyl butanoate.
