1. Drawing structural formulas for branched chain alkanes:
Use the parent chain name to draw out the parent chain. Attach the alkyl groups according to their location. Fill all carbons with the appropriate number of hydrogens so each carbon will have four covalent bonds.
Ex. Draw the structural formula for 5-ethyl-4,5-dimethyl-3- propylheptane

2. Ex. Draw the structural formula for 5-ethyl-4,5-dimethyl-3-propylheptane
Draw the parent chain
Draw the branches
Fill the carbons with hydrogens

3. Is this the proper name?

4. Line drawing
