The series in which the molecular formula of adjacent members differ by a CH 2 unit is called homologous series and the individual members are called homologous.
Alkenes are often used as a synonym of olefin. The general characteristics of this series are. An unsaturated hydrocarbon that contains at least one carboncarbon double bond with the general formula C n H 2n.
What is an alkene in chemistry. These are very detailed and comprehensive notes developed by team of expert faculties. If a simple unbranched alkane is converted to a cycloalkane two hydrogen atoms one from each end of the chain must be lost.
Definitions of organic compounds. Note that this is the same as the alkane formula except that we subtract two hydrogen atoms to allow for the double bond. Density Alkenes are lighter than water.
