What is the IUPAC name for the compound with the structure CH3-CH(CH3)-C(CH3)2-CH3?

Step 1: Identify the longest continuous chain of carbon atoms in the structure CH3-CH(CH3)-C(CH3)2-CH3. Count the number of carbon atoms in this chain.
Step 2: The longest chain has 4 carbon atoms, which is called a butane chain.
Step 3: Identify the positions of the branches (methyl groups) on the longest chain. There are three methyl groups attached to the second and third carbon atoms.
Step 4: Number the carbon atoms in the longest chain from one end to the other to determine the correct positions for the substituents.
Step 5: Write the IUPAC name by combining the names of the substituents with the name of the longest chain. The substituents are 'methyl' and the longest chain is 'butane'.
Step 6: The final IUPAC name is 2,3,3-trimethylbutane, indicating that there are three methyl groups on the second and third carbons of the butane chain.
