Consider the given chemical reaction sequence : [figure] Total sum of oxygen atoms in Product A and Product B is .
Answer
14
Solution
[figure]
A = phenol-2,4-disulphonic acid; B = 2,4,6-trinitrophenol (picric acid)
∵ –SO3H groups are replaced by –NO2 and the third –NO2 enters C-6 (phenol is not oxidised)
O atoms: A = 1 (OH) + 2 × 3 (SO3H) = 7 ; B = 1 (OH) + 3 × 2 (NO2) = 7
∴ Total = 7 + 7 = 14
Answer: 14
