JEE Main 2026 Chemistry question
The mass of benzanilide obtained from the benzoylation reaction of 5.8 g of aniline, if yield of product is 82%, is g (nearest integer). (Given molar mass in g mol⁻¹ H:1, C:12, N:14, O:16)
Answer: 10
Solution
Moles of aniline = 5.8/93 = 0.0623. With 82% yield, mass of benzanilide = 0.0623×0.82×197 ≈ 10 g.
