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 ...
The general formula of alkanes is CnH2n, while those of alkenes is CnH2n+2. True or false? A. True B. False Correct Answer B. False ExplanationThe general formula of alkanes is CnH2n, while the general formula of alkenes is CnH2n+2: alkanes have twice the number of hydrogen ...

General formula: With the increase of the number of carbon atoms, the melting point and boiling point of olefins increase in general, and change from gaseous to liquid state. When the number of C atoms is less than or equal to 4, it is gaseous. There are C = C olefin structure, its...
Alkenes are acyclic hydrocarbons with one carbon to carbon double bond and the general molecular formula. They are named using a similar naming rule for alkanes; now, they have changed only the suffix to –ene. Alkenes are unsaturated hydrocarbons with the molecular formula CnH2n. ...
They have a CH3 at each end of the molecule. What differs is the number of CH2 groups between the two ends. It is possible to build up a series by simply adding an extra CH2 group This leads to a general formula of CnH2n+2 hydrogen carbon n= 1 n=2 n=3 n=4 Structure of ...
The simplest acyclic alkenes, with only one double bond and no other functional groups, form an homologous series of hydrocarbons with the general formula CnH2n. 6-1 IUPAC Rules for Alkene and Cycloalkene Nomenclature 1. The ene suffix (ending) indicates an alkene or cycloalkene. ethene ...
