HOMEWORK The o:p ratio in the mononitration of bromobenzene

1. HOMEWORK The o:p ratio in the mononitration of bromobenzene has been reported to be 38:62. Using this ratio and the amount of 4-nitrobromobenzene you obtained, calculate the experimental yield of your reaction? 2. Why is the bromobenzene added in portions over a 15-min period rather than all at once ? 3. Explain why 4-nitrobromobenzene predominates in the product mixture. 4. Why is dinitration not a significant process under the conditions used ? 5. What the is function of the concentrated sulfuric acid in this experiment ? 6. Why is the reaction flask shaken frequently during the addition of the bromobenzene to the acid mixture? 7. 8. Is the nitration reaction exothermic or endothermic ? What compounds are present in th…
