Step-by-Step Verified Solution

JEE Main 2022 (Online) 27th July Evening Shift Chemistry - Practical Organic Chemistry Question 32 English Explanation
Moles =592=\frac{5}{92}

Moles of benzaldehyde produced =592×0.92=0.05=\frac{5}{92} \times 0.92=0.05

∴\therefore Mass of benzaldehyde formed

=0.05×106=0.05 \times 106

=5.3 g=5.3 \mathrm{~g}

=530×10−2=530 \times 10^{-2}
