Questions & Step-by-Step Solutions
Which of the following is the correct IUPAC name for 2-methylpropene?
Step 1: Identify the base name of the compound. The base name is 'prop' because the longest carbon chain has three carbon atoms.
Step 2: Determine the type of compound. Since there is a double bond, we use 'ene' in the name.
Step 3: Identify the position of the double bond. In 2-methylpropene, the double bond is between the first and second carbon atoms, so we use 'prop-1-ene'.
Step 4: Identify the substituents. There is a methyl group (CH3) on the second carbon, so we add '2-methyl' to the name.
Step 5: Combine the parts to form the full name. The full IUPAC name is '2-methylprop-1-ene'.
