Experiment 1 :Alkanes&Alkenes:Combustion and action of sulphuric acid. Introduction In the study of organic chemistry‚ the organic compounds which are made up of carbon and hydrogen are called hydrocarbons. They can be gases as‚ propane‚ they can be liquids‚ for example‚ benzene‚ or they can be low-melting solids and waxes‚ for example‚ polystyrene. There are four classifications of hydrocarbons; saturated hydrocarbons or alkanes‚ unsaturated hydrocarbons or alkenes and alkynes‚ cycloalkanes‚ and

Four isomers were attained and then relative reactivity rate was calculated. 1‚1-dichlorobutane had 2.5% per Hydrogen; 1‚2-dichlorobutane had 10%; 1‚3-dichlorobutane had 23%; and 1‚4-dichlorobutane had 9.34% per Hydrogen. Introduction Alkanes are relatively unreactive. There are only a few types of reactions commonly performed. In this lab‚ halogenation was performed
