Any of a group of hydrocarbons whose carbon atoms form chains linked by one or more double bonds. Alkenes have the general formula CnH2nand include ethylene. Also calledolefin. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mifflin Harcourt Pub...
What is the general formula for an alkene? Properties of alkenes An alkene is a hydrocarbon (a molecule that contains carbon and hydrogen atoms) that has a double bond between 2 of the carbons in the carbon chain. Similar to alkanes, the first 3 alkenes are colorless gases. Alkenes that ...
These compounds have the general formula:\nwherein R and R', which may be the same or different, are hydrogen or alkyl, preferably C1-C4 alkyl, and X, Y and Z are each independently hydrogen, chlorine or fluorine, provided that when R, R' and Z are hydrogen, X and Y are not ...
