JEE Main 2025 Chemistry question
What amount of bromine will be required to convert 2 g of phenol into 2, 4, 6-tribromophenol ? (Given molar mass in g mol⁻¹ of C, H, O, Br are 12, 1, 16, 80 respectively)
Answer: (1)
Solution
Moles of phenol = 2/94 = 0.021; moles of Br2 needed = 3×0.021=0.064; mass = 0.064×160=10.22g.
