Question

A solution of 20.2 g of 1,2 -dibromopropane in MeOH upon heating with excess Zn produces 3.58 g of an unsaturated compound X . The yield (%) of X is closest to [Atomic weight of Br is 80]

MARKS Content Team · Accepted Answer

Correct answer: (B) 85. Moles of 1,2 -dibromo propane =20.2/202=0.1 mole Moles of prop-1-ene =3.58/42 =0.085 mole % yield =0.085/01×100=85%

A solution of $20.2 g$ of $1, 2$ -dibromopropane in $M e O H$ upon heating with excess $Z n$ produces $3.58 g$ of an unsaturated compound $X .$ The yield ( $%$ ) of $X$ is closest to [Atomic weight of Br is $80$ ]
