Question

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)

Accepted Answer

Correct answer: 20. (20) Reaction suggests that 1 mole of aniline give 1 mole of orange dye. so ( mol )_ aniline= ( mole )_ orange dye 9.3 g93 g mol^-1= mass of orange dye199 g mol^-1 mass of orange dye=19.9 g ≃20 g

$9.3 g of pure aniline upon diazotisation followed by coupling with phenol gives an orange dye. The mass of orange dye produced (assume 100 ∖ % yield/conversion) is_______g. (nearest integer)$
