1
Q
How are Halogenoalkanes formed?
A
Hydrogen halide adds across the double bond of an alkene to produce a halogenoalkane; HCl, HBr, and HI – hydrogen halides are gases at room temperate and are bubble into liquid alkanes.

Q
What is the Hydration of an alkene?
A
- Steam + Alkene -> Alcohol (High temperature/pressure – presences of phosphoric acid catalyst) known as hydration of an alkene.
