What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
What is an example of an exothermic reaction and why it's an exothermic reaction?
There are so many examples of exothermic reactions that is the reactions in whoch energy is released. All the oxidation reactions are exothermic reactions . similarly hydrogenation of alkenes like ethene,cyclohexene etc. are also exothermic reactions with different energies being released during these reactions. The cause for release of energy during these reactions is simple, if the energy relleased due to formation of new bonds that is the bonds of products is more than the energy consumed for breaking the bonds of reactants then such reactions are exothermic. So, ENTHALPY CHANGE =Bond energy of reactants - Bond energy of Products The amount of energy released is thus dependent on the values of bond energies. For example in case of hydrogenation of cyclohexene, Benzene and Cyclooctene these values are 120 kj/mole, 210 kj/mole and 23 kcal/mole respectively
What is the process used to turn liquid oils into more highly saturated solid fats?
Hydrogenation .
What is the catalyst used for hydrogenation of oils?
Due to fast reaction and increase D20 value or Hardness and low quantity of Hydrogen gas used catalysts are required for the reaction to be usable , as non catalytic hydrogenation takes place only at very high temperatures
How do you prepare isopentene through hydrogenation?
To synthesiise isopentene by hydrogenation you will need to selectively hydrogenate isoprene. Selective hydrogenation of di-olefines is a tricky process with limited numbers of licensors. Normally isopentene is extracted from C5 raffinate.
Can pt and pd be used in the hydrogenation of alkenes?
Pt and Pd can be used as catalyst in the hydrogenation of alkenes or (de)hydrogenation of hydrocarbons (cracking in petrol industry)
What is hydrogenation used to do?
Hydrogen is used in many things. For example It is used as rocket fuel.
What is the raw material used to obtain ethane by hydrogenation?
ethene
Is Hydrogenation is used to convert alkenes and alkynes to alkanes?
True
How can hydrogenation be applied in magarine production?
In the production of margarine, hydrogenation is the process used to control the consistency of the product.æ When oil is hydrogenated it becomes solid or partially solid.
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.

How can you use the word hydrogenation in a sentence?
Margarine is produced by the hydrogenation of vegetable oils.
The hydrogenation of 2-methylpropanal gives the product?
hydrogenation of 2-methylpropanal gives
What is the process of fat hydrogenation?
The process of fat hydrogenation involves a high temperature and the involvement of a metallic catalyst. The metallic catalyst either increases or decreases the number of the chemical bonds within the molecules of the substances.
