Quinoline "poisons" the Lindlar catalyst, thereby enhancing its selectivity. This prevents the hydrogenation reaction from going from the alkyne to the alkane, and instead from the alkyne to the alkene.

Is Hydrogenation is used to convert alkenes and alkynes to alkanes?
True
How can you obtain cis and trans alkene from alkynes?
Add bulky groups on alkynes as iodination of alkynes which always give trans di-iodo products then substitution of iodine atoms with other groups produce other trans products for cis alkenes simply perform the controlled hydrogenation.
What are the only types of alkynes which can form acetylides?
Terminal alkynes can form acetylides.
When liquid oils are turned into solid fats through a process?
This process is called hydrogenation.
Why alkynes are called acetylenes?
alkynes are those hydrocabons wich have triple co alent bond among carbon atoms . The first member of alkyne series is known as acetylene.This is the sim;lest alkyne ,with molecular formula( C2H2).Alkynes are also called acetylenes because of the name of the first member of the series is actylene.

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 are the only types of alkynes which can form acetylides?
Terminal alkynes can form acetylides.
How old is Quinoline Yellow?
Electronic musician Luke Williams, aka Quinoline Yellow, is 38 years old (birthdate: August 18, 1978).
When is a hydrocarbon molecule classified as an alkyne?
Actually all hydrocarbons are not alkynes, but all alkynes are hydrocarbons. Alkynes contain carbon and hydrogen and hence they are known as hydrocarbons.
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
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 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.
What is an aporphine?
An aporphine is a member of a class of quinoline alkaloids from which apomorphine can be derived.
When liquid oils are turned into solid fats through a process?
This process is called hydrogenation.
