1-Methylcyclohexene is treated with different reagents. For which reagents does the major product contain two stereocentres (formed as a racemate)?

Hydroboration-oxidation gives trans-2-methylcyclohexanol (C-1 and C-2 are stereocentres). Bromine gives 1,2-dibromo-1-methylcyclohexane (C-1 and C-2 are stereocentres). Acid hydration gives 1-methylcyclohexanol and HBr gives 1-bromo-1-methylcyclohexane, which have no stereocentre.
