The stereocenter of this molecule is the only carbon that makes 3 visible carbon bonds.
Work Step by Step
1. Look for all the carbons that are making at least 3 visible 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. ** Don't forgot the Hydrogen. If a carbon follow this rule, it is a stereocenter.
