D) 74
Correct Answer: D
Solution :
\[\underset{?}{\mathop{\underset{0.037}{\mathop{R-OH}}\,}}\,+{{C}_{2}}{{H}_{5}}MgI\xrightarrow{{}}\underset{\underset{22400cc}{\mathop{11.2cc}}\,}{\mathop{{{C}_{2}}{{H}_{6}}}}\,+RMgI\] \[\because \]11.2 cc gas is evolved by alcohol = 0.037 g \[\therefore \] 22400 cc gas will be evolved by alcohol \[=\frac{0.037}{11.2}\times 22400\] \[=74g\]You need to login to perform this action.
