The alkanes are a homologous series with a structure based on a carbon chain ... Polymers close polymerA large molecule formed from many identical smaller molecules known as monomers.

with chemical structures of up to six carbon atoms. The new discovery doubles the number of carbon atoms found in a single molecule on Mars. The alkane molecules are significant in the search for ...

The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, resulting in a very slow loss of amber bromine color. The radical bromine atoms ...
