Please explain dehydrogenation...?

Question

how is it done to an alkane or alkene?

Answer 1

Dehydrogenation is the removal of hydrogen. Two processes by which this can be done is by:

1. Free Radical Halogenation
CH3-CH3 + X2 ---->CH3-CH2-X + H-X
(wher X = F, Cl, Br, or I)

2. Catalytic Dehydrogenation
CH3-CH3 ---->CH2=CH2 + H2
(a catalyst such as platinum needs to be added when performing this reaction).

Answer 2

dehydrogenation is the removal of hydrogen usually from a hydrocarbon chain. a saturated chain has a hydrogen at all possible bonds with the carbon atoms. as the molecule becomes more and more dehydrogenated, these locations lose their hydrogen and free up the bond capacity for other atoms

Answer 3

I worked in aroma chemicals for quite a while, and we used a pressure autoclave with a catalyst for small-scale dehydrogenation of aromatic alkyl and alkylidene hydrocarbons.
