Final answer:
To draw the structural formula of 2-bromo-3,3,4,4-tetramethylhexane, start with a six-carbon chain, add a bromine to the second carbon, and two methyl groups each to the third and fourth carbons.
Step-by-step explanation:
The task is to draw the structural formula of 2-bromo-3,3,4,4-tetramethylhexane. To begin with, you need to draw a hexane molecule, which is a chain of six carbon atoms. Then, you add a bromine atom (Br) on the second carbon (C) of the chain to represent the '2-bromo-' part of the name. After this, you add two methyl groups (CH3) each to the third and fourth carbon atoms. Methyl groups are depicted as "-CH3" branching off the main chain. Remember, each carbon atom should have four bonds in total, so the rest of the bonds not shown are understood to be with hydrogen atoms (H), which are not explicitly drawn for clarity.
