In the above reaction, 3 . 9   g of benzene on nitration gives 4 . 92   g of nitrobenzene. The percentage yield of nitrobenzene in the above reaction is _________ % . (Round off to the Nearest Integer). (Given atomic mass : C   : 12 . 0   u ,   H   : 1 . 0   u   O   : 16 . 0   u , N   : 14 . 0   u )

Correct answer

0

Step-by-step solution

3 . 9   gm    123 78 × 3 . 9 = 6 . 15   gm But actual amount of nitrobenzene formed is 4 . 92   gm and hence. Percentage yield = 4 . 92 6 . 15 × 100 = 80 %
