15.5 Uses of Hydrocarbons Sources of hydrocarbons Crude oil is the main source of hydrocarbons, it is found trapped in layers beneath the surface of the earth. Crude oil is a complex mixture of hydrocarbons - alkanes, cycloalkanes and aromatic compounds. [ Note:...
15.4 Reactions of Alkenes Electrophilic addition Unlike alkanes, alkenes are more reactive because they are unsaturated and contain a C=C bond. A C=C bond contains a σ bond and a π A π bond is a region of high density of electron which is open to attack...
15.3 Introduction to Alkenes What is an alkene? Alkenes are unsaturated hydrocarbons which contain at least one carbon-carbon double bond(C=C) bond. They form the homologous series with the general formula of CnH2n. The physical properties of alkenes are similar to...
15.2 Reactions of Alkanes Reactivity of alkanes Alkanes are saturated and generally unreactive because they are non-polar, hence they are unattractive towards nucleophiles and electrophiles Alkanes will only react with non-polar reagents in the presence of heat or...
15.1 Introduction to Alkanes What is an alkane? A hydrocarbon is a compound containing carbon and hydrogen atoms Examples of hydrocarbons are alkanes, alkenes, alkynes and arenes. Alkanes are saturated hydrocarbons, the carbon atoms are joined to each...
CHAPTER 15: Hydrocarbons Introduction to Alkanes Reactions of Alkanes Introduction to Alkenes Reactions of Alkenes Uses of Hydrocarbons Learning outcomes: show awareness of the general unreactivity of alkanes, including towards polar reagents describe the...
