Lesson Worksheet: Phenol Chemistry
In this worksheet, we will practice describing the physical and chemical properties of phenol.
Phenol can be prepared from a benzene derivative. The scheme shows the products and reaction conditions for the preparation of phenol:
What are the reactants and ?
- ABromobenzene and
- BSodium benzoate and
- CChlorobenzene and
- DBromobenzene and
- EChlorobenzene and
Which of the following best describes this reaction?
The table shows the physical properties of three aromatic compounds: benzene, phenol, and toluene. Which column corresponds to phenol?
|Melting Point ()||40.5||5.5|
|Boiling Point ()||181.7||80.1||111|
|Appearance||Crystalline solid||Colorless liquid||Colorless liquid|
|Solubility in Water at||8.30||1.80||0.52|
A student wants to test whether they have a solution of phenol. In two separate experiments, they add iron(III) chloride and bromine water to samples of the solution, as shown.
What color will the solution change to if phenol is present when iron(III) chloride is added?
What color change will be observed if phenol is present when bromine water is added?
- AOrange to green
- BOrange to colorless
- COrange to purple
- DOrange to red
- EOrange to blue
Which of the following is incorrect about phenol?
- AIt can be prepared by fractional distillation of coal tar.
- BIt is less acidic than alcohols.
- CIt cannot react with hydrochloric acid.
- DIt reacts with formaldehyde, forming Bakelite.
- EIt is a corrosive substance.
The molecular structure shown is for Bakelite, a synthetic polymer:
Bakelite can be formed from the reaction of phenol with a molecule in acidic or basic conditions. Which molecule is it?
- CFormic acid
What type of polymerization process does the production of Bakelite involve?
- CRing opening
What small molecule is produced during the reaction?
