Q8 / 54 · JEE Advanced 2022 (Paper 1) · Chemistry

If the reaction sequence given below is carried out with $15$ moles of acetylene, the amount of the product $D$ formed (in $g$ ) is
The yields of $A, B, C$ and $D$ are given in parentheses.
[Given: Atomic mass of $H = 1, C = 12, O = 16, Cl = 35$ ]

Correct answer: 136

Solution

Molecular formula of $D$ is $C_{8} H_{8} O_{2}$
Molar mass of $D$ is $(12 \times 8 + 8 \times 1 + 16 \times 2) = 136 g$
$∴$ Mass of $D$ is $136$

Hence, the correct answer is 136.
