There isn't one with butanol, but there is with butanal.

#### Explanation:

I think you mean butanal, not butanol. There is no addition reaction with butanol because it has no $\pi$-bonds anywhere.

With butanal, it looks like

${C}_{4} {H}_{8} O + {H}_{2} O \to {C}_{4} {H}_{10} {O}_{2}$

or, in structural form,

The double bond on the fourth carbon opens to allow a hydroxyl group, which then lets the original oxygen bond to the remaining hydrogen.
