The former child star who played comedienne Roseanne Barr's eldest daughter on Roseanne was left embarrassed during a recent interview when she let it slip she had no idea her Tv dad John Goodman died in the series finale, which aired in 1997.
1 Alkanes are Saturated Hydrocarbons. 2  They consist of the elements Carbon and Hydrogen, and all the bonds between the Carbon atoms are single bonds. 3  They have the general formula CnH2n+2.4  Since all Alkanes are similar in structure and properties, they are called a Homologous Series. Alkanes are Saturated Hydrocarbons. 2  They consist of the elements Carbon and Hydrogen, and all the bonds between the Carbon atoms are single bonds. 3  They have the general formula CnH2n+2.
There are three types of unsaturated hydrocarbons: alkenes, alkynes and aromatic hydrocarbons. Alkenes have one or more carbon-carbon double bond. Alkynes have one or more carbon-carbon triple bond, and aromatic hydrocarbons have a benzene or aromatic ring in their structure.ydrocarbons are compounds that only consist of the elements hydrogen and carbon. In this lesson, we will focus on one type of hydrocarbon: unsaturated hydrocarbons, and its three types-alkenes, alkynes and aromatic hydrocarbons.
