Unsaturated hydrocarbons in the presence of pt hydrogenation called |
|
Answer» It is called alkene. Addition of hydrogen to a carbon-carbon double bond is called hydrogenation. The overall effect of such an addition is the reductive removal of the double bond functional group. Regioselectivity is not an ISSUE, since the same group (a hydrogen atom) is bonded to each of the double bond carbons. The simplest source of two hydrogen atoms is molecular hydrogen (H2), but mixing alkenes with hydrogen does not result in any discernible reaction. Although the overall hydrogenation reaction is exothermic, a high ACTIVATION ENERGY prevents it from taking PLACE under normal conditions. This restriction may be circumvented by the use of a catalyst, as shown in the following diagram. Hope it will be helpful for you.... If you like my answer do follow me...
