2-butanol can be formed as the only product of the Markovnikov addition of H2O to two different alkenes. In contrast, 2-octanol can be formed as the only product of the Markovnikov addition of H2O to just one alkene. To examine the difference, draw the alkene starting materials of each alcohol. Draw the bond-line (skeletal) structures of the two alkene starting materials that can be used to synthesize 2-butanol via Markovnikov hydration.
