# How would you write a chemical equation for addition reactions to produce 3-hydroxy-3-methylhexane?

The hydration of an alkene follows the Markovnikov rule: The $\text{H}$ atom adds to the carbon atom that already bears more hydrogen atoms.
Thus, the $\text{H}$ adds to $\text{C2}$ and the $\text{OH}$ adds to $\text{C3}$.
