How many chiral centers does the following molecule contain?

Organic reactions can often be classified into two broad categories: substitution and elimination. Substitution reactions substitute one substituent for another. Elimination reactions typically form after the wholesale removal of a substituent, with no replacement. Below are examples of two types of reactions.

Reaction 1:

Reaction 2:

A scientist is studying the rate of reaction 1. He wants to double the rate of the reaction, but is unsure how to increase concentrations of the reactants. Which of the following is true?

Which alcohol will react most rapidly via an SN1 mechanism?

Ephedrine (shown below) contains what type of amine?

The process of glycolysis is used by all cells of the body to turn glucose into ATP for cellular energy. When stores of glucose are low, however, the body can break down a form of stored glucose in the liver to increase glucose reserves. The supply of glycogen is limited, and eventually the body must break down free fatty acids (FFAs) through a process called beta-oxidation.

Which organ in the body cannot perform beta-oxidation, thus requiring the use of ketone bodies when stores of glucose are depleted?

What is the purpose of the formation of lactic acid during anaerobic respiration?

Acetyl-CoA is a react in the citric acid cycle, while and are products. If twelve molecules of are produced over a period of time, how many molecules are produced during this period?

Which of the following statements is true concerning the Hofmann elimination reaction?

Ephedrine (shown below) contains what type of amine?
