JEE Mains · Chemistry · STD 12 - 6. Haloalkanes and Haloarenes
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 \(\mathrm{g} \mathrm{mol}^{-1} \mathrm{H}: 1, \mathrm{C}: 12, \mathrm{O}: 16\), \(\mathrm{Br}: 80)\)
- A 180
- B 184
- C 188
- D 192
Answer & Solution
Correct Answer
(B) 184
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \text { Molecular mass of } \mathrm{Q}=230 \mathrm{~g} \mathrm{~mol}^{-1} \\ & \begin{aligned} \text { Mass of } \mathrm{Q} & =0.8 \times 230 \\ & =184 \mathrm{~g}\end{aligned}\end{aligned}\)
