Cracking , Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst.

What conditions are needed for catalytic cracking to happen?

Catalytic cracking requires specific conditions such as high temperature (typically between 450-550°C) and moderate pressure. The presence of a catalyst, usually a solid acid catalyst like zeolite, is essential to facilitate the breaking of larger hydrocarbon molecules into smaller, more valuable products like gasoline and diesel. Additionally, a controlled feedstock composition and proper residence time in the reactor are important for optimizing the cracking process.


A chemical reaction in a living cell occurs in the presence of a specific protein molecule?

The specific protein molecule in a cell acts as a catalyst, facilitating the chemical reaction to occur more efficiently or at a faster rate. The protein molecule binds with the reactants, stabilizes the transition state, and lowers the activation energy required for the reaction to proceed. Without the presence of this protein molecule, the reaction may occur, but at a significantly slower rate.


What has 3 tails and can be saturated or unsaturated?

A triglyceride molecule has 3 fatty acid tails attached to a glycerol backbone, and these fatty acid tails can be either saturated or unsaturated depending on the presence of double bonds in the hydrocarbon chain.


What is the major organic product that results when 3-heptyne is hydrogenated in the presence of Lindlar's catalyst?

The major organic product formed when 3-heptyne is hydrogenated in the presence of Lindlar's catalyst is 3-heptene. Lindlar's catalyst is a poisoned palladium catalyst that selectively reduces alkynes to cis alkenes.


What is the reaction of an alkene and water in the presence of an acid catalyst to produce an alcohol called?

The reaction of an alkene and water in the presence of an acid catalyst is called an acid-catalyzed hydration reaction. This reaction forms an alcohol.

What are the two necessary conditions for cracking to take place?

The two necessary conditions for cracking to take place are high temperature and presence of a catalyst. High temperature allows for the breaking of chemical bonds in the hydrocarbon molecules, while the catalyst accelerates the cracking reaction by providing an alternative pathway with lower activation energy.


How does the alkene to alkane reaction occur?

The alkene to alkane reaction occurs through a process called hydrogenation, where hydrogen gas is added to the alkene molecule in the presence of a catalyst, such as platinum or palladium. This results in the breaking of the double bond in the alkene, converting it into a single bond in the alkane.


What is the process by which a molecule gains an H atom?

The process by which a molecule gains an H atom is called hydrogenation. It involves the addition of a hydrogen atom to a molecule typically in the presence of a catalyst, such as a metal like platinum or nickel. This process can alter the physical and chemical properties of the molecule.

How does a hydrocarbon react with an acid?

Hydrocarbons typically do not react with acids under normal conditions. However, in the presence of a strong acid or a catalyst, hydrocarbons can undergo reactions such as acid-catalyzed hydration to form alcohol or ester formation.

What are two conditions needed to crack paraffin?

Two conditions needed to crack paraffin are high temperature (around 500-900 degrees Celsius) and the presence of a suitable catalyst. Cracking breaks down larger hydrocarbon molecules like paraffin into smaller, more valuable hydrocarbons like ethylene and propylene.


How does a hydrocracker work?

A hydrocracker is a high-pressure, high-temperature catalytic reactor that uses hydrogen in the presence of a catalyst to break down heavy hydrocarbon molecules into lighter and more valuable products like gasoline and diesel. The process involves breaking carbon-carbon bonds and saturating carbon-carbon double bonds with hydrogen, resulting in improved fuel quality and increased yield of valuable products.
