Answer 2

Statement D is false regarding the phenol molecule.

• The attraction forces that exist between molecules govern a substance's boiling point. Between phenol molecules, hydrogen bonding exerts a stronger attraction than Van der Waals forces between alkane molecules. Phenol has a higher boiling point than hydrocarbons because of hydrogen bonding.
• Intermolecular hydrogen bonding occurs in phenol.
• Phenol glows pink when exposed to air owing to gradual oxidation. Phenol is oxidized to quinone, and then quinone mixes with phenol to produce phylloquinone, which is pink in color.
• Phenol is mildly dissolved in water but highly soluble in alcohol and ether.
• Thus, assertion D is wrong, and therefore the answer.
