Consider the above sequence of reactions. 151 g of 2-bromopentane is made to react. Yield of major product P is

80 \%

whereas Q is

100 \%

.
Mass of product Q obtained is ____ g.
(Given molar mass in

\mathrm{g} \mathrm{mol}^{-1} \mathrm{H}: 1, \mathrm{C}: 12, \mathrm{O}: 16

\mathrm{Br}: 80)

Correct answer

Step-by-step solution

\begin{aligned} & \text{ Molecular mass of } \mathrm{Q}=230 \mathrm{ g} \mathrm{ mol}^{-1} \\ & \begin{aligned} \text{ Mass of } \mathrm{Q} & =0.8 \times 230 \\ & =184 \mathrm{ g}\end{aligned}

\end{aligned}$
