The general formula of the alkanes is \({C_n}{H_{2n + 2}}\). They are insoluble in water. The names, molecular formula and the structural formula of the first eight alkanes must be learned.

The formula of any alkane can be worked out using the general formula C n H 2n+2 where n = the number of carbon atoms.

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...
