3.1 explain the terms homologous series, hydrocarbon, saturated, unsaturated, general formula and isomerism.

Organic chemistry introduction

homologous series: a series of organic compounds that have the same general formula, similar chemical reactions and where each member differ from the next by a given formula.

hydrocarbon: a compound only containing carbon and hydrogen

saturated: an organic compound in which all the bonds are single bonds

unsaturated: an organic compound that contains a carbon- carbon double bond

general formula: a formula that states the ratio of atoms of each element in the formula of every compound in a particular homologous series

isomerism: compounds that have the same molecular formula but different formulae are said to exhibit isomerism, the different compounds are called isomers
