How many stereoisomers are possible for the compound shown below?

Step-by-step solution

The IUPAC name of the given compound is 4,6-dimethylheptan-2-ol. Analyzing the carbon atoms for chirality: C-2 is bonded to - H , - OH , - CH ₃ , and - CH ₂ CH ( CH ₃) CH ₂ CH ( CH ₃)₂ . All four groups are different, so C-2 is a chiral center. C-4 is bonded to - H , - CH ₃ , - CH ₂ CH ( OH ) CH ₃ , and - CH ₂ CH ( CH ₃)₂ . All four groups are different, so C-4 is a chiral center. C-6 is bonded to - H , a complex alkyl group, and two identical - CH ₃ groups. Since two groups are identical, C-6 is achiral. The wedge
