Chemistry- alkanes and alkenes the process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols there are, however, a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. A short test paper and markscheme to assess pupil understanding of alkanes & alkenes. The addition of water to an alkene in the presence of a catalytic amount of strong acid leads to the formation of alcohols (hydroxy‐alkanes) this reaction proceeds via a standard carbocation mechanism and follows the markovnikov rule the mechanism for the addition of water to ethene follows 1 . The alkenes are distinguished from the alkanes by the fact that they contain two less hydrogen atoms than the alkane with the same carbon backbone because the alkenes have two fewer hydrogen atoms, they contain a carbon–carbon double bond.
