When propene is treated with hydrogen chloride in ethanol, one of the
products of the reaction is ethyl isopropyl ether. Write a plausible
mechanism that accounts for the formation of this product.

2.

When, in separate reactions, 2-methylpropene, propene, and ethene are
allowed to react with HI under the same conditions (i.e., identical
concentration and temperature), 2-methylpropen is found to react fastest
and ethene slowest. Provide and explanation for these relative rates.

I think that this occurs because monosubstituted alkenes are more stable
then alkenes with no substituents therefore, the reaction with
2-methylpropene is more sterioselective and regioselective.
