When the product (P) is subjected to Carius analysis using \(AgNO_3\), \(1.0\) 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)
- A 1
- B 2
- C 3
- D 4
Answer & Solution
Correct Answer
(A) 1
Step-by-step Solution
Detailed explanation
The given reactant is p-nitrotoluene. Step (i): Reduction with Sn/HCl followed by \(OH^-\) converts the \(-NO_2\) group to an \(-NH_2\) group, yielding p-toluidine. Step (ii): Reaction with acetic anhydride, \((CH_3CO)_2O\), protects the amino group by forming…
