Functional Classes I, Structure and Naming - Organic Chemistry Concepts: An EFL Approach - page 40

D The alkyl substituents are a methyl group at C 2 and two ethyl groups at C 4 and C 5 .
List the substituents in alphabetical order and the IUPAC name can be generated.

4,5-Diethyl-2-methylheptane
Note that numbers are separated by commas, and number and letters are separated
by hyphens. Finally, the final substituent and the parent name are written as one word.
