Given a generic Alkyne such as R-C triple bond C-R + H2 results in a H-C-R=H-C-R structure, with both H's on top and both R's on the bottom, as drawn in a CIS structure.

What is the role of quinoline in the hydrogenation of alkynes?
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 C5H10 alkane or alkene?
The general formula for alkenes is 'CnH2n'. Sp for C5H10 Substituting for 'n' it becomes C5H(2(5)) = C5H10 . Hence itv is an Alkene.
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.
When hydrogen is added to ch3ch2chchch3 the reaction is an?
... addition reaction; the hydrogen molecule is split, one of its atoms is added to each carbon atom that is initially double bonded, and an alkene becomes an alkane. --- ... known as hydrogenation.
Which of the alkyl chlorides undergoes dehydrohalogenation in the presence of a strong base to give pent-2-ene as the only alkene product?
Which of the alkyl chlorides undergoes dehydrohalogenation in the presence of a strong base to give pent-2-ene as the only alkene product - the choices are: A 2-chloropentane B 1-chloro-2-methylbutane C 1-chloropentane D 3-chloropentane The answer is: 3-chloropentane
What does the hydrogenation of an alkene gives?
two atoms of hydrogen add to the carbons in a double bond of an alkene to form an alkane.

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

Is turpentine an alkane or alkene?
It is an alkene
Why can the cracking of an alkane into an alkene not be described as oxidation since the alkane loses two hydrogens?
Technically it can be described as oxidation. Technically it is an oxidation reaction, although I've never heard it described as "the oxidation of an alkane". Strange, since when an alkene is converted to an alkane by hydrogenation, we do hear it called "reduction of an alkene". Perhaps this is because the term "alkane oxidation" has been appropriated for the promising research into efficiently capturing energy by combining alkanes with oxygen at low temperatures.
Is 1-nonene an alkane alkene or an alcohol?

Is cyclopentene an alkane alkene or alcohol?
