1
Q

How do you make a Phenol?

A

Add a hydroxyl group to a benzene ring.

2
Q

What happens if you put a Phenol in water?

A

It forms a weak acid solution, as hydrogen ions dissociated off the -OH group.

3
Q

What is the equation for Phenol + Water?

A

C6H5OH + aq C6H5O- + H+.

4
Q

What happens when you add sodium hydroxide to a phenol?

A

Phenol is neutralised by sodium hydroxide. It forms a salt and water. The salt is sodium phenoxide. C6H5OH + NaOH -> C6H5O-Na+ + H2O.

5
Q

What is the equation for Phenol + Reactive metal?

A

2C6H5OH + 2Na -> 2C6H5O-Na+ + H2. This effervesces and produces Hydrogen gas. The organic product, a salt, is sodium phenoxide.
