3. Phenol
• In organic chemistry, a class of chemical
compounds consisting of a hydroxyl group
(—OH) bonded directly to an aromatic
hydrocarbon group. The simplest of the
class is phenol, which is also called
carbolic acid 𝐶6 𝐻5OH.
Aniline
• Aniline is an organic compound consisting
of a phenyl group(C6H5) attached to an
amino group (—NH2) .The formula is
C6H5NH2.

6. Resonance of Phenol
Phenol is acidic in nature. It will lose Hydrogen cation to form Phenoxide ion which is more
stable than Phenol. Resonance structures of Phenol:

10. Resonance of Aniline
Basicity: Aniline is a weak base. ... Traditionally, the weak basicity of aniline is attributed to a
combination of inductive effect from the more electronegative sp2 carbon and resonance effects,
as the lone pair on the nitrogen is partially delocalized into the pi system of the benzene ring.
