JEE Main 2025 — 2 April, Evening Shift — Question 22

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)

Answer: 184

Numerical answer — enter this value.

Molecular mass of $\mathrm{Q}=230 \mathrm{~g} \mathrm{~mol}^{-1}$

Mass of $\mathrm{Q}=0.8 \times 230=184 \mathrm{~g}$
