Consider the following reactions sequence When the product (P) is subjected to Carius analysis using AgNO₃ , 1.0 g of the product (P) will produce _______ g of the precipitate of AgBr. (Nearest Integer) (Given: molar mass in g mol ⁻¹ C : 12, H : 1, O : 16, N : 14, Br : 80, Ag : 108)

Step-by-step solution

The given reactant is p-nitrotoluene. Step (i): Reduction with Sn/HCl followed by OH^- converts the -NO₂ group to an -NH₂ group, yielding p-toluidine. Step (ii): Reaction with acetic anhydride, (CH₃CO)₂O , protects the amino group by forming N-(4-methylphenyl)acetamide. Step (iii): Bromination with Br₂/AlBr₃ directs the incoming bromine to the ortho position relative to the strongly activating -NHCOCH₃ group (the para position is blocked by the methyl group). This yields 2-bromo-4-methylacetanilide. Step (iv): Acid
