A hydroxyl group attached directly to a benzene ring.
1 of 10
Is 2-phenylethanol a phenol?
No, as the -OH group is not directly attached to the benzene ring.
2 of 10
Is phenol soluble in water?
Yes, slightly. This is because the -OH group forms hydrogen bonds with the water molecules.
3 of 10
Which is more soluble in water, phenols or alcohols?
Alcohols: the benzene ring in phenol makes is less soluble in water than with ordinary alcohols.
4 of 10
Is 2-ethylphenol a phenol?
Yes, as the -OH group is attached directly to the benzene ring.
5 of 10
Are phenols acidic or basic?
Phenols are weakly acidic due to the -OH group.
6 of 10
Phenol + NaOH = ____________.
Sodium phenoxide (C₆H₅O⁻Na⁺) + Water.
7 of 10
Phenol + Sodium metal = ___________.
Sodium phenoxide (C₆H₅O⁻Na⁺) + Hydrogen gas.
8 of 10
Uses of phenols.
Production of aspirin, paints (azo dyes), antiseptics and disinfectants (such as TCP) and found in detergents.
9 of 10
Which is the most reactive; phenol or benzene?
Phenol. The lone pair of electrons on the oxygen atom merge with the delocalised ring of electrons, increasing the negativity of the ring. This makes the molecule more reactive.
