Identify the product [D] formed when Reactant [A] \((M M 78 \mathrm{~g} / \mathrm{mol})\) undergoes the series of reactions shown
- A m-Cresol
- B Benzoic acid
- C o-Cresol
- D p-Cresol
Answer & Solution
Correct Answer
(B) Benzoic acid
Step-by-step Solution
Detailed explanation
The reactant [A] has a molar mass of \(78\) g/mol, which corresponds to benzene (\(C_6H_6\)). In the first step, benzene reacts with methyl chloride (\(MeCl\)) in the presence of a catalyst (Friedel-Crafts alkylation) to form toluene (\(C_7H_8\)). In the second step, toluene…
