Can alkanes make polymers
WebApr 8, 2016 · Pressure and heat energy open the double bonds in the alkene and make it bond to form large polymer molecules. Alkenes are unsaturated hydrocarbons, meaning they don't have all the hydrogen that they could do, because of the double bond between some of the carbons. Under large amounts of energy - from heat and pressure … WebAlkenes are generally more desirable than alkanes as they are more reactive due to the presence of the carbon-carbon double bond, so they can take part in reactions in which alkanes cannot, making them more useful than alkanes; They are used to make polymers and are the starting materials for the production of many other chemicals

WebThe first four members of the alkanes are methane, ethane, propane and butane. Alkane molecules can be represented in the following forms: (C₂H₆ or drawn out version). Students should be able to recognise substances as alkanes given their formulae in these forms. 4.7.2 Reactions of alkenes and alcohols. 4.7.2.2 Reactions of alkenes WebAlkenes can be used to make polymers and the hydrogen used to make ammonia. Kerosene and diesel oil are often cracked to produce petrol, other alkenes and hydrogen. Cracking involves heating the hydrocarbon molecules to around 600 – 700°C to vaporise them. The vapours then pass over a hot powdered catalyst of alumina or silica.
