Phenols

Question 0

Properties

Answer 0

White solid at room temp
Polar and can form H bonds
Slightly soluble in water

Question 1

More reactive because…

Answer 1

Oxygens lone pair interact with ring

Makes H δ+ making it easier to from off

Question 2

Combustion

Answer 2

Incomplete

Requires a lot of oxygen

Question 3

Test for phenol

Answer 3

React with Iron (lll) Chloride to form purple solution

Question 4

Phenol with H2O

Answer 4

Forms Phenoxide (Phenate) ion and proton acted water molecule

Question 5

Phenol with NaOH

Answer 5

Forms a salt
H drops of and Na attaches
OH deprotonates phenol

Question 6

Phenols with sodium

Answer 6

H drops off and Na attaches

Question 7

Phenol with Carboxylic acids

Answer 7

Doesn’t react as readily as aliphatic alcohols
Very slow reaction
acid chlorides used instead –> cl is a better leaving group

Question 8

Phenol with Bromine

Answer 8

Aqueous solution of Bromine and phenol
White ppt formed
Goes from red/brown to colourless
Rapid at Room temp

Question 9

Phenol and nitric acid

Answer 9

Rapid at room temp

Mix of 2- &4- nitro phenols and water
