Determine the product X:
Correct answer: B. Option B
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
To introduce nitro group in the aniline ring, the reagents used are conc.HNO3 and conc.H2SO4 which are very strong acids. Amino group of aniline is a very strong base so it has great affinity towards these acids. Therefore, we need to protect amino group first by reacting aniline with acetic anhydride. Then, the acetanilide formed is reacted with conc.HNO3 and conc.H2SO4 to introduce nitro group at the para position. Nitro group is introduced at para position because the para position is the most active site as it has the highest electron density. p-nitroacetanilide is hydrolysed to form p-nitroaniline.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
