Chapter 23- Alkenes

Alkenes

Unsaturated hydrocarbons with double bonds between two carbon atoms.

HYDRATION

________: In the presence of phosphoric (V) acid, 300 degrees celsius temperature and 60 atm pressure, alkenes react with steam to form alcohols.

Double bonds

________ are broken into single bonds.

BROMINATION

________: when ________ is added to an alkene, it immediately decolourises as the double bonds are broken and ________ atoms join the alkene.

Alkenes

________ can also be combusted.

An alkane can be broken in three ways using cracking

Making one alkane and one alkene, and one hydrogen, making two alkenes and hydrogen, making an alkane

Hydrogenation

Chemical reaction between molecular hydrogen and another compound or element, usually in the presence of a catalyst such as nickel.

Bromination

Chemical reaction that entails the introduction of one or more halogens into a compound.

Hydration

Hydration reaction is a chemical reaction in which a substance combines with water.

Addition reaction

A chemical reaction in which only one product is formed.

Saturated

Compounds with a single covalent bond between carbon atoms.

Unsaturated

Compounds with a double covalent bond between its carbon atoms.

Polyunsaturated

Compounds with more than one double covalent bonds between its carbon atoms.
