This chapter surveys compounds of carbon and hydrogen only. It works through alkanes (naming, preparation, properties, free-radical halogenation and conformations), alkenes (the double bond, cis-trans isomerism, preparation and addition reactions including Markovnikov's rule and the peroxide effect), alkynes (the triple bond, acidity and additions) and benzene (resonance, aromaticity, electrophilic substitution and directive influence), ending with the toxicity of some aromatic hydrocarbons.
Also called: alkanes, alkenes and alkynes · aromatic hydrocarbons · benzene
