Normal alkanes C n H 2n+2 are extended linear chain molecules that form ordered lamellar structures and crystals. When the size of the chains reaches n > 120, such ultra-long alkanes manifest chain ...

For example the formula of ethane is C 2 H 6. The ratio of C:H atoms is 2:6. The empirical formula of an alkane is based on the simplest ratio of carbon to hydrogen atoms: the simplest form of the C:H ...
