1-Methylcyclohexene is subjected to (i) $\mathrm{BH}{}_3$ in THF; (ii) $\mathrm{H}{}_2\mathrm{O}{}_2$, $\mathrm{NaOH}$. The major product (racemic) is

Boron adds to the less substituted carbon (C-2) and H adds to C-1 on the same face (syn addition). Oxidation replaces B by OH with retention, so OH at C-2 and the new H at C-1 are cis, which puts the C-1 methyl and the C-2 OH trans. The product is trans-2-methylcyclohexan-1-ol. 1-Methylcyclohexan-1-ol would form by oxymercuration or acid hydration.
