The reactivity of alkenes in an acid-catalyzed hydration reaction depends on the stability of the carbocation intermediate that is formed during the reaction. The more substituted the carbocation, the more stable it is.

Here are the steps to determine which alkene is most reactive:

1. Identify the carbocation that would form from each alkene. For ethene, it would be a primary carbocation. For propene, it would be a secondary carbocation. For 2-methylpropene, it would be a tertiary carbocation. For 1-butene, it would also be a secondary carbocation.

2. Determine the stability of each carbocation. Tertiary carbocations are more stable than secondary carbocations, which are more stable than primary carbocations.

3. The alkene that forms the most stable carbocation will be the most reactive.

So, the answer is C, 2-methylpropene, because it forms a tertiary carbocation, which is the most stable among the options given.
