What is the correct IUPAC name for the compound with the structure CH3-CH2-CH(CH

What is the correct IUPAC name for the compound with the structure CH3-CH2-CH(CH3)-CH2-CH3?

What is the correct IUPAC name for the compound with the structure CH3-CH2-CH(CH3)-CH2-CH3?

Step 1: Identify the longest continuous chain of carbon atoms in the structure. Count the number of carbon atoms.
Step 2: In the given structure CH3-CH2-CH(CH3)-CH2-CH3, the longest chain has 5 carbon atoms.
Step 3: Name the longest chain. Since it has 5 carbon atoms, it is called 'pentane'.
Step 4: Look for any branches (substituents) on the longest chain. In this case, there is a methyl group (CH3) attached to the third carbon.
Step 5: Number the carbon atoms in the longest chain starting from the end closest to the branch. The methyl group is on the third carbon.
Step 6: Combine the branch name and the longest chain name. The methyl group is on the third carbon, so it is named '3-methyl'.
Step 7: Put it all together. The correct IUPAC name for the compound is '3-methylpentane'.
