Discuss the hydration of alkanes, water and steam

Alkanes are saturated hydrocarbons, meaning they contain only single carbon-carbon and carbon-hydrogen bonds. Due to their stable, nonpolar nature, alkanes are generally unreactive and do not undergo direct hydration reactions with liquid water or steam under normal conditions.

However, alkanes can react with steam at very high temperatures in the presence of a catalyst in a process known as steam reforming. This is an important industrial process used to produce synthesis gas (a mixture of carbon monoxide and hydrogen).

For example, the steam reforming of methane (the simplest alkane) is:

$$\mathrm{CH_4(g) + H_2O(g) \xrightarrow{Ni \text{ catalyst}, 700-1100^\circ C} CO(g) + 3H_2(g)}$$

In this reaction, steam acts as an oxidizing agent, breaking the C-H bonds in methane to form carbon monoxide and hydrogen. This is not a typical "hydration" in the sense of adding water across a double bond, but rather a high-temperature catalytic reaction with steam.
