Catalysts are used in substitution reactions of saturated compounds to increase the rate of the reaction by lowering the activation energy barrier. This allows the reaction to proceed more quickly and under milder conditions, making it more efficient and cost-effective. Additionally, catalysts can also help improve the selectivity of the reaction by favoring the formation of the desired product.

Why you use nickel as a catalyst?
Nickel is used as a catalyst in various reactions because it is cost-effective, readily available, and has good catalytic properties, such as high activity and selectivity. It is often used in hydrogenation reactions, where it promotes the conversion of unsaturated compounds to saturated compounds.
What is the difference in structure between a saturated and an unsaturated compound?
the difference in structure between a saturated and an unsaturated compound is found in their bonds. A Saturated compound contain only one carbon-carbon signle bond. all the four bonds of carbon are fully utilised and no more hydrogen or other atoms can attach to it. Thus, they can undergo only substitution reactions. (aka ALKANES). An Unsaturated Compound contain one double covalent bond between carbon atoms or a triple covalent bond between carbon atoms. the bonds of carbon are not fully utilised by hydrogen atoms, more of these can be attached to them. Thus, they undergo addition reactions as they have two or more hydrogen atoms less than the saturated hydrocarbons
What is most reactive benzene or ethane.?
Benzene is generally more reactive than ethane due to its unique structure and the presence of a conjugated π-electron system. While ethane is a saturated hydrocarbon that primarily undergoes reactions such as combustion and substitution, benzene can participate in electrophilic aromatic substitution reactions due to its delocalized electrons. This makes benzene more susceptible to reactions with electrophiles. However, benzene's stability also means it is less reactive in some conditions compared to alkenes or alkynes.
Why double or triple bonds are unsaturated compounds?
Double and triple bonds are considered unsaturated because they contain fewer hydrogen atoms than their saturated counterparts, which only have single bonds. In a saturated compound, every carbon atom is bonded to as many hydrogen atoms as possible, whereas the presence of double or triple bonds means that some hydrogen atoms are replaced by additional carbon-carbon bonds. This characteristic allows unsaturated compounds to undergo reactions such as hydrogenation, where additional hydrogen can be added to convert them into saturated compounds.
Why are aromatic compounds saturated?
Because, In alkenes&alkynes,there exists atleast One double bond(pi bond) which is relatively weaker than sigma bond(There are no pi bonds in alkanes.Hence they are saturated).Hence they are unsaturated.
Why butane undergoes substitution reactions?
Butane undergoes substitution reactions because it can be easily replaced by another group due to the presence of weak C-H bonds. This allows for the substitution of hydrogen atoms in the butane molecule with different functional groups, leading to the formation of new compounds with altered properties.
What has the author Nicolas George Samman written?
Nicolas George Samman has written: 'Reactions of saturated hydrocarbons on some supported metal catalysts'
How do saturated double bonds affect the stability of organic compounds?
Saturated double bonds increase the stability of organic compounds by reducing reactivity and making the molecule less likely to undergo chemical reactions.
Why you use nickel as a catalyst?
Nickel is used as a catalyst in various reactions because it is cost-effective, readily available, and has good catalytic properties, such as high activity and selectivity. It is often used in hydrogenation reactions, where it promotes the conversion of unsaturated compounds to saturated compounds.
Does propane undergo addition reaction?
Propane does not typically undergo addition reactions due to its stable structure as a saturated hydrocarbon. It is not reactive under normal conditions and tends to undergo combustion or substitution reactions rather than addition reactions.
What are the reagents used distingush saturated and unsaturated organic compounds?
Basically there are many tests which is usually practiced to distinguish saturated Organic compounds from the unsaturated ones. But two of them are the most common: 1. Bromine water test. 2. Bayer's test. Basically Bromine water is red in color, so when an unsaturated compound (Alkene or Alkyne) is treated with it. The Bromine water get decolourized, on the other side the color is not changed when treated with saturated compound. In the Bayer's test KMnO4 solution is used, the unsaturated compound vanish its pink color while the saturated compounds do not.

Why is hydrogenation with a catalyst considered an addition reaction?
It doesn't. Catalysts merely speed reactions along, they do not make them happen - that is the definition of a catalyst. Industrially, catalysts are important in making chemical reactions economically fast.
What compounds have saturated bonds?
Compounds with saturated bonds have all carbon-carbon bonds that are single bonds. Examples include alkanes like methane, ethane, and propane. These compounds are often referred to as saturated hydrocarbons because they contain the maximum number of hydrogen atoms bonded to each carbon atom.
What is most reactive benzene or ethane.?

How do you tell if a compound is saturated by looking its formula?
saturated compounds have the general formula CnH2n+2
What is a unsaturated compound?
An unsaturated organic compound is one which has double or triple bonds in Carbon atoms. When all the bonds are single then the compound is called saturated. In unsaturated compounds the carbon atom will be in sp or sp2 hybridised state and in saturated compounds the carbon will be in sp3 hybridised state. Unsaturated compounds are identified by the reaction with bromine water which is pink in color. The pink color is lost due to addition of Bromine to the multiple bond. Aromatic compounds like benzene also contain double bonds but not considered as unsaturated. They do not give addition reactions under normal conditions.
