The stereocenter of this molecule is the carbon connected to the hydroxyl (OH) group.

Work Step by Step

1. Look for all the carbons that are making at least 3 bonds. ** If a carbon has less than 3 visible bonds, it means that it has 2 hydrogens (equal groups) or has a double bond. Therefore, it can't have 4 different groups, so it can't be the stereocenter. 2. Since we know that there is only 1 stereocenter, find the carbon that has 4 different groups connected to it. - In this case, it can't be the carbon on the left (1), because it is making 2 bonds with the same "cyclo" group, and it is equal for both sides. ** Don't forgot the Hydrogen. If a carbon follows this rule, it is a stereocenter.
