Use the following information to answer the next question.
Many organic reactions are used to convert hydrocarbons found in petroleum into petrochemicals that are that are used to make plastics and a wide range of other products. For example, ethene is produced from ethane provided from petroleum refiners by processing it under certain conditions.
The process by which ethene is produced from ethane is called

e) polymerization
a) addition
The process by which ethene is produced from ethane is called cracking.
To answer the question, we need to identify the process by which ethene is produced from ethane.
To do this, let's go through each option and see which one matches the given information:
a) Destructive distillation: Destructive distillation is a process where organic substances are heated to high temperatures in the absence of oxygen, resulting in the breakdown of the molecules into smaller fragments. This process is commonly used in the production of coke, coal gas, and coal tar. It is not the correct answer for this question, as it does not specifically match the process of producing ethene from ethane.
b) Catalytic reforming: Catalytic reforming is a refining process used to convert low-octane naphthas into high-octane gasoline. It involves rearranging the hydrocarbon molecules under the influence of a catalyst. This process is not the correct answer for the given question as it does not involve the production of ethene from ethane.
c) Cracking: Cracking is the process of breaking down larger hydrocarbon molecules into smaller ones. It is commonly used to convert heavy hydrocarbon fractions into lighter ones, such as the conversion of ethane into ethene. This process matches the description provided in the question, making it the correct answer.
d) Fractional distillation: Fractional distillation is a process that separates a mixture of liquids with different boiling points. It is commonly used in the petroleum industry to separate crude oil into different fractions according to their boiling points. Although it is part of the overall refining process, it is not specifically related to the production of ethene from ethane.
e) Hydrocarbon conversion: Hydrocarbon conversion is a broad term that refers to various processes involving the chemical transformation of hydrocarbon molecules. While the production of ethene from ethane does involve hydrocarbon conversion, it is not as specific as the cracking process mentioned earlier.
Based on the information provided, the correct answer is:
c) Cracking
Cracking is the process used to convert ethane (a hydrocarbon found in petroleum) into ethene, which is used to make plastics and other products.
