Predict the major organic product of the following reaction.

d. Is the reaction of 1-butene with HBr regioselective?

e. Is it stereoselective?

f. Is it stereospecific?

Which major product is formed in the acid-catalyzed hydration of ${\mathrm{CH}}_3$-${\mathrm{CH}}_2$-${\mathrm{CH}}_2$=${\mathrm{CH}}_2$ (3-methyl-1-butene)?

Predict the product of the following reaction.

The second-order rate constant (in units of M^-1s^-1) for acid-catalyzed hydration at 25 °C is given for each of the following alkenes:

a. Calculate the relative rates of hydration of the alkenes. (Hint: Divide each rate constant by the smallest rate constant of the series: 3.51 × 10^-8.)

b. Why does (Z)-2-butene react faster than (E)-2-butene?

c. Why does 2-methyl-2-butene react faster than (Z)-2-butene?

d. Why does 2,3-dimethyl-2-butene react faster than 2-methyl-2-butene?

a. Draw the product or products that will be obtained from the reaction of cis-2-butene and trans-2-butene with each of the following reagents. If a product can exist as stereoisomers, show which stereoisomers are formed.

7. H₂O + H₂SO₄

b. With which reagents do the two alkenes react to form different products?

What is the product of the reaction of maleate and H₂O when H₂SO4 is used as a catalyst instead of fumarase?
