A mixture of nitric acid and sulfuric acid was added to an equimolar mixture of C6H6, C6H6Z, C6H6Y. After warming and stirring for a few minutes the nitrated products were analyzed and found to consist of the products C6H4YNO2, C6H5NO2, and C6H4ZNO2 in the ratio of 750:30:1, respectively. Which of the following can be deduced from this data?
a. the Z group is a deactivator
b. the nitro group is a meta director
c. the Y group is a deactivator
d. benzene is the least reactive
e. the Z group is an ortho‐para director
Answer: a. the Z group is a deactivator
