Which of the following is the correct structure for 2,3-dimethyl-2-butanol?

Step 1: Identify the main chain of the molecule. In this case, it is a butanol, which means it has four carbon atoms in a straight chain.
Step 2: Number the carbon atoms in the main chain starting from one end. The numbering should start from the end closest to the hydroxyl (OH) group.
Step 3: Place the hydroxyl (OH) group on the second carbon atom, as indicated by the name '2-butanol'.
Step 4: Identify the 'dimethyl' part of the name. This means there are two methyl (CH3) groups attached to the carbon chain.
Step 5: Since it is '2,3-dimethyl', place one methyl group on the second carbon and another methyl group on the third carbon.
Step 6: Ensure that the final structure has the hydroxyl group on the second carbon with two methyl groups on the same carbon.
