Complete the following with appropriate structures :
`2,3 "-Dinitroaniline" underset ((ii) Anisol) overset ((i) NaNO_2 and HCl at 5^@ c) rarr (A)``.

Explanation

To solve the problem, we need to follow the steps of the reaction involving 2,3-dinitroaniline and anisole, with the reagent NaNO2 and HCl.

### Step 1: Identify the structure of 2,3-dinitroaniline
2,3-Dinitroaniline is an aniline derivative with two nitro groups (-NO2) at the 2 and 3 positions of the benzene ring, and an amino group (-NH2) at the 1 position. The structure can be represented as follows:
