To do well in GCSE science, Year 10 and Year 11 students will need to know what hydrocarbons and alkenes are. They're found in crude oil and have many uses, from fuel to construction materials. Have a go at this interactive AQA Syllabus A quiz and revise what you've learned about their chemistry. Petroleum refining - Petroleum refining - Saturated molecules: The simplest of the hydrocarbon molecules is methane (CH4), which has one carbon atom and four hydrogen atoms per molecule. The next simplest, ethane (C2H6), has two carbon atoms and six hydrogen atoms. A whole class of hydrocarbons can be defined by expanding upon the relationship between methane and ethane. Known as the paraffins One of the topics studied in the chemistry section of GCSE science is hydrocarbons. These are the compounds of carbon and hydrogen found primarily in crude oil and used to make fuels. To aid your revision, have a go at this fun AQA Syllabus A quiz and go over what you learned in Year 10 and Year 11.

Mineral oil hydrocarbons (MOHs) are complex chemical mixtures. MOHs are generally derived from crude oil. They mainly consist of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). MOSH comprise open-chain, often branched hydrocarbons (commonly named paraffins) and cyclic, saturated hydrocarbons (commonly
