Verified Solution

Answer & Solution

Correct Answer

(A) 175

Step-by-step Solution

Detailed explanation


\(\begin{aligned}
& \mathrm{M}=\left(\mathrm{C}_6 \mathrm{H}_4\right)_2\left(\mathrm{C}_6 \mathrm{H}_5\right)_2 \mathrm{C}_2 \mathrm{H}_4 \mathrm{O} \\
& =350
\end{aligned}\)
Weight of product of \(S=350 \times 1 / 2=175 \mathrm{gm}\) Ans.
