Identify the final product formed when Toluene undergoes a series of reactions with reagents given in the order:
(i) \(\mathrm{Cl}_2\) / Sunlight
(ii) \(\mathrm{H}_2 \mathrm{O} / 373 \mathrm{~K}\)
(iii) Acetophenone / \(\mathrm{OH^-}\) at \(293 \mathrm{~K}\)
- A p-Hydroxyacetophenone
- B 2, 4-Dichloroacetophenone
- C 4-Chloro-2-hydroxyacetophenone
- D 1, 3-Diphenylprop-2-en-1-one
Answer & Solution
Correct Answer
(D) 1, 3-Diphenylprop-2-en-1-one
Step-by-step Solution
Detailed explanation
Toluene reacts with \(\mathrm{Cl}_2\) in the presence of sunlight to undergo free radical chlorination at the side chain, yielding benzal chloride, \(\mathrm{C}_6\mathrm{H}_5\mathrm{CHCl}_2\). Hydrolysis of benzal chloride with \(\mathrm{H}_2\mathrm{O}\) at \(373 \mathrm{~K}\)…

\(\begin{aligned}
& 2 \mathrm{No}(g) \rightleftharpoons \mathrm{N}_2+\mathrm{O}_2 ; K_{\mathrm{G}_1}=2.4 \times 10^{20} \\
& \mathrm{No}(g)+\frac{1}{2} \mathrm{Br}_2(\mathrm{~g}) \rightleftharpoons \mathrm{NoBr}(g) ; K_{C_2}=1.4
