Answer 1

Крекинг октана: С8H18=C4H10+C4H8
Изомеризация гексана:CH3-CH2-CH2-CH2-CH2-CH3 -----------AlCl3, t---------> CH3-CH2-CH(CH3)-CH2-CH3

Answer 2

Cracking of Octane (3 variants):

1. Thermal Cracking: This process involves the breaking of octane molecules at high temperatures and pressures, typically in the presence of a catalyst. It is used to produce lighter hydrocarbons such as ethylene and propylene [[1]]. 2. Catalytic Cracking: In this method, octane molecules are broken down using a catalyst, which helps to lower the required temperature and pressure. This process is commonly used in petroleum refineries to produce gasoline and other valuable products [[2]]. 3. Hydrocracking: Hydrocracking combines the use of heat, pressure, and hydrogen to break down octane molecules into smaller fragments. This process is often used to convert heavy hydrocarbons into lighter, more valuable products such as gasoline and diesel fuel [[3]].

Isomerization of Hexane:

Isomerization is a process that involves rearranging the atoms within a molecule to form different isomers. In the case of hexane, isomerization can produce various isomers, such as 2-methylpentane, 3-methylpentane, and 2,2-dimethylbutane.

The isomerization of hexane is typically carried out using a catalyst, such as platinum or palladium, at elevated temperatures and pressures. This process is commonly used in the petroleum industry to convert straight-chain hydrocarbons into branched isomers, which have higher octane ratings and better combustion properties. By isomerizing hexane, the resulting isomers can be used to improve the quality of gasoline by increasing its octane number [[4]].
