Question

When aniline reacts with oil of bitter almonds $$\left( {{C_6}{H_5}CHO} \right)$$   condensation takes place and benzal derivative is formed. This is known as

A. Million's base
B. Schiff's reagent
C. Schiff's base  
D. Benedict's reagent
Answer :   Schiff's base
Solution :
Benzaldehyde reacts with primary aromatic amine to form schiff's base
\[\underset{\text{Benzaldehyde}}{\mathop{{{C}_{6}}{{H}_{5}}CH}}\,=O+\underset{\text{Aniline}}{\mathop{{{C}_{6}}{{H}_{5}}N{{H}_{2}}}}\,\to \underset{\text{Benzylidene aniline}}{\mathop{{{C}_{6}}{{H}_{5}}CH=N{{C}_{6}}{{H}_{5}}}}\,\]
