Give two separate conditions under which long chain hydrocarbons can be cracked.
Dodecane, $\text{C}_{12}\text{H}_{26}$, is a long chain hydrocarbon found in crude oil and may be cracked to produce but-2-ene and an alkane. Write a balanced equation for this reaction.
The reactions of but-2-ene are shown. In the boxes below, write the structural formulae of organic compounds A to D.
Draw the skeletal formula for compound D.
Using the letters A to D where relevant, identify the compounds that are chiral. If there are none, write "none".
But-2-ene can undergo polymerisation to produce poly(butene). Draw the structural formula of part of the poly(butene) chain showing two repeat units.
Compound C is a liquid that can be treated with concentrated sulfuric acid to form a gas, E, which will decolourise aqueous bromine when bubbled through it. Suggest the structural formula of E.
Suggest the structural formula of the product formed when E reacts with excess bromine.
Identify the type of reaction that occurs between E and an excess of bromine.
