Organic chemistry：練習題

What observation would you expect when bromine water is added to a sample containing an alkene?

During the process of cracking, large hydrocarbon molecules are broken down into smaller, more useful molecules. Which of the following describes the typical organic products of this reaction?

Hydrocarbons can be cracked using different methods. Which of the following describes the specific conditions required for the method known as steam cracking?

Which of the following is the correct general formula for the homologous series of alkanes?

In the fractional distillation of crude oil, different fractions are separated based on their boiling points. Which statement correctly describes the temperature gradient inside the fractionating column?

A hydrocarbon fuel is burnt in a plentiful supply of oxygen. Write a balanced chemical equation for the complete combustion of propane, \(C_{3}H_{8}\).

Decane, \(C_{10}H_{22}\), can be cracked to produce ethene and one other product. Calculate the molecular formula of the other product formed when two molecules of ethene, \(C_{2}H_{4}\), are produced from one molecule of decane, and state why this process is economically important in the petrochemical industry.
