The high melting point and insolubility in organic solvents of sulphanilic acid are due to its $......$ structure.

Identify the product $C$ in the following reaction sequence:
$C_6H_5COOH$ $\xrightarrow{NH_3, \Delta} A$ $\xrightarrow{Br_2, KOH} B$ $\xrightarrow{CHCl_3, KOH} C$

In the reaction: $\text{Primary Amine} + CHCl_3 + KOH \rightarrow \text{Product}$,what is the product?

The reaction given below is known as:
$ArN_2^+ X^- + Cu_2Cl_2 + HCl \to ArCl + N_2 + Cu_2Cl_2$

Assertion : Anilinium chloride is more acidic than ammonium chloride.
Reason : Anilinium ion is resonance stabilized.
