Alkenes

Question 1

What are alkenes?

Answer 1

Alkenes are unsaturated hydrocarbons (contain a carbon carbon double bond) (consists of a normal covalent bond)

Question 2

As alkenes contain a carbon - carbon double bond, which is an area of high electron density, what does this allow electrophiles to do?

Answer 2

Allows them to be attacked by electrophiles
( Species that are attracted to S- areas)

Question 3

Name the chemical we use to identify carbon carbon double bonds and other unsaturated compounds. Give the observation

Answer 3

Bromine water - turns the solution from orange - brown to colourless if a double bond is present
