Q59.The major products from the following reaction sequence are product A and product B. The total sum of π electrons in product A and product B are _______ (nearest integer) Q60. 9.3 g of pure aniline upon diazotisation followed by coupling with phenol gives an orange dye. The mass of orange dye produced (assume 100\% yield/conversion) is _______ g. (nearest integer)
What This Question Tests
This question tests the understanding of the diazotisation of aniline followed by a coupling reaction with phenol to form an azo dye, and then requires a stoichiometric calculation to determine the mass of the product.
