... have a double bond between two of the carbon atoms, is also a hydrocarbon. they have two fewer hydrogen, makes them unsaturated. double bond can open up to be a single bond so 2 carbons can bond with something else, makes them very reactive

Alkenes

1 of 9

First 4 ... are : Ethene, propene, butene and pentene and they have the general formula: CnH2n

Alkenes

2 of 9

In a lot of .. alkenes combust completely. Not enough ... in air to do that so they undergo incomplete combustion. Carbon and carbon monoxide produced. Incomplete combustion results in a yellow smoky flame, less energy is released.

Oxygen

3 of 9

A ... group is a group of atoms which determine how the molecule typically reacts. All alkenes have the same ... group

Functional

4 of 9

Addition of hydrogen is called ... Alkene reacts with Hydrogen with a catalyst present

Hydrogenation

5 of 9

Steam reacts with alkenes to form ... Alkenes react with steam, water is added across double bond and ... formed

alcohol

6 of 9

... are long molecules formed when small molecules (monomers) join together - polymerisation, high pressure and a catalyst. Plastics are usually made up of ... -usually carbon based and monomers are often alkenes

Polymers

7 of 9

Monomers that make up ... have a double covalent bond. Lots of unsaturated monomer molecules (alkenes) can open up their bonds and join to make polymer chains- called addition polymerisation. When monomers react, the only product is the polymer

Addition polymers

8 of 9

General formula of these is CnH2n+1OH, they all contain an OH group. First 4 in the homologous series are: Methanol, Ethanol, Propanol and Butanol
