Which statement best describes hydration of alkenes?

The hydration of alkenes involves the addition of water (H₂O) to the double bond of an alkene, which ultimately leads to the formation of an alcohol. This process typically requires conditions of high temperatures and often the presence of an acid catalyst.

When steam is introduced to an alkene in these conditions, the alkene reacts with water to form an alcohol through a process known as acid-catalyzed hydration. Among the options, the statement that describes this process accurately involves the use of steam at high temperatures to produce alcohols. This highlights the necessary conditions and the resultant product that hydration achieves, differentiating it from the other processes associated with alkenes, such as hydrogenation, halogenation, or reactions that occur at room temperature without precise conditions.
