Q. Explain the structure of Alkenes?
Ans.
Alkenes have the general formula CnH2n. Therefore, for every n carbon atoms, there are 2n hydrogen atoms.
Alkenes have C = C double bonds and are therefore unsaturated.
Ethene (also called ethylene) and is the first member of the alkene series:
Ethylene is made by passing ethanol vapor over heated aluminum oxide which acts a catalyst.
E1cb means elimination, unimolecular, of the conjugate base. This type elimination proceeds through the carbanion mechanism. An carbon compound, acting as an acid, is attacked by
