Electron Dot Structure Of Methane Ethane Propane Butane Pentane Hexane. Methane ch 4 and ethane c 2 h 6. In the following representations these hydrocarbons are drawn first as condensed structural formulas that show all carbons and hydrogens.
Longer chains are named as follows. The structure of alkanes. A two carbon chain is called ethane.
The structure of alkanes.
The next three alkanes are propane butane and pentane. To name an alkane first identify the longest chain of carbon atoms in its structure. A three carbon chain propane. As the chain length numbers of carbons increases the melting and boiling points of the alkanes gradually increase for these compounds.
