What is the name of this compound?
The name is 4-(1-methylethyl)heptane.
Step 1. Find the longest continuous carbon chain.
The longest continuous chain is marked by the horizontal red line.
It has seven carbon atoms, and it contains only
Step 2. Number the carbon atoms from one end to the other.
Step 3. Locate and identify the side-chains.
There is a group attached to carbon 4.
Its longest continuous chain contains two carbon atoms, so it is an ethyl group.
It has a methyl group attached to carbon 1 (the carbon that is attached to the main chain), so it is a 1-methylethyl group.
Step 4. Insert the name of the group with its locating number in front of the name of the parent chain.
The group is attached to carbon 4 of the parent chain, so the name of the compound is 4-(1-methylethyl)heptane.
NOTE: The names of groups that contain numbers are enclosed in parentheses.
