QuestionAnswer
Cracking is the process of breaking down large hydrocarbons into smaller ones.Cracking
What is the breaking down process of large hydrocarbons into smaller ones called?The breaking down process is called cracking.
Smaller hydrocarbons are more useful for fuel compared to long hydrocarbons.Usefulness of Smaller Hydrocarbons
Smaller hydrocarbons are considered more useful for fuel than what?Smaller hydrocarbons are more useful for fuel than long hydrocarbons.
Crude oil contains more long hydrocarbons than needed and not enough shorter ones.Composition of Crude Oil
What is the typical composition of hydrocarbons in crude oil?Crude oil contains more long hydrocarbons than needed and not enough shorter ones.
Cracking is done to break down longer hydrocarbons into smaller ones to meet the demand for fuel.Purpose of Cracking
Why is cracking performed on hydrocarbons from crude oil?Cracking is performed to break down longer hydrocarbons into smaller ones to meet the demand for fuel.
Catalytic cracking is a method of cracking where hydrocarbons are passed over a hot catalyst at low pressure.Catalytic Cracking
What is catalytic cracking, and what conditions are involved?Catalytic cracking is a method where hydrocarbons are passed over a hot catalyst at low pressure.
Steam cracking involves long hydrocarbons reacting with steam at high temperatures.Steam Cracking
What is steam cracking, and what conditions are involved?Steam cracking involves long hydrocarbons reacting with steam at high temperatures.
The products of cracking are a mixture of smaller alkanes and alkenes.Products of Cracking
What types of hydrocarbons are produced as a result of cracking?The products of cracking include a mixture of smaller alkanes and alkenes.
Alkanes and alkenes are different types of hydrocarbons.Alkanes and Alkenes
What distinguishes alkanes from alkenes in terms of their chemical structure?Alkanes and alkenes are different types of hydrocarbons.
Alkenes are described as unsaturated because they have 2 fewer hydrogen atoms than alkanes with the same number of carbon atoms.Unsaturated Hydrocarbons
Why are alkenes considered unsaturated hydrocarbons?Alkenes are described as unsaturated due to having 2 fewer hydrogen atoms than alkanes with the same number of carbon atoms.
Alkanes are described as saturated because they have the maximum possible number of hydrogen atoms.Saturated Hydrocarbons
Why are alkanes considered saturated hydrocarbons?Alkanes are described as saturated because they have the maximum possible number of hydrogen atoms.
Alkenes can be used to make polymers (plastics) and a range of other chemical products.Applications of Alkenes
What applications are associated with alkenes?Alkenes can be used to make polymers (plastics) and a range of other chemical products.
