Draw the skeletal structure for 2,2-dibromo-3-chlorohexanoic acid.

The name "2,2-dibromo-3-chlorohexanoic acid" indicates:

• "hexan-" means a 6-carbon chain.
• "-oic acid" means it is a carboxylic acid ($\text{COOH}$), which is the principal functional group. The carbon of the carboxylic acid group is always designated as carbon 1.

• "2,2-dibromo" means there are two bromine atoms ($\text{Br}$) attached to carbon 2.
• "3-chloro" means there is one chlorine atom ($\text{Cl}$) attached to carbon 3.

• Carbon 1 ($\text{COOH}$): This carbon is double-bonded to one oxygen, single-bonded to another oxygen (which is bonded to hydrogen), and single-bonded to carbon 2. It already has 4 bonds, so no hydrogens are attached directly to C1.
• Carbon 2: This carbon is bonded to C1, C3, and two $\text{Br}$ atoms. It has 4 bonds, so no hydrogens are attached to C2.
• Carbon 3: This carbon is bonded to C2, C4, and one $\text{Cl}$ atom. It has 3 bonds, so it needs 1 hydrogen atom.
• Carbon 4: This carbon is bonded to C3 and C5. It needs 2 hydrogen atoms.
• Carbon 5: This carbon is bonded to C4 and C6. It needs 2 hydrogen atoms.
• Carbon 6: This carbon is bonded to C5. It needs 3 hydrogen atoms.

Starting from the carboxylic acid end (C1):
