Example Questions

Example Question #1 : Help With Rate Calculations And Kinematics

What kinetic equation describes the rate of an E1 process?

Possible Answers:

None of these

Correct answer:

Explanation:

Most organic reactions are carried out in multiple steps. The rate equation can be derived from the process that occurs in the slowest step of the mechanism. An E1 reaction's slow step is when a leaving group separates from the hydrocarbon and a carbocation is formed. The only reactant in this step is one molar equivalent of the hydrocarbon. Thus, the rate equation only depends on that substance. The molar equivalent determines the exponent of each reactant in the equation.

Example Question #2 : Reaction Energetics And Kinetmatics

Generally, when compared to the rate of inorganic reactions, the rate of organic reactions is __________.

Possible Answers:

Slower, because organic compounds are ionic

Faster, because organic compounds are ionic

Faster, because organic compounds contain covalent compounds

Slower, because organic compounds contain covalent bonds

Correct answer:

Slower, because organic compounds contain covalent bonds

Explanation:

By and large, organic compounds contain mainly covalent bonds. Covalent bonds are typically harder to break, which is why organic reactions happen at a relatively slower rate than inorganic reactions.
