It is important to realize that in aromatic substitution the actual electrophilic substituting agent, ⊕ X or δ ⊕ X − δ ⊖ Y, is not necessarily the reagent that is added to the reaction mixture. For example, nitration in mixtures of nitric and sulfuric acids is not brought about by attack of the nitric ... Webb15 nov. 2012 · For the most part, grading of the formal report usually starts out with a grade of 25 points out of 30 maximum points or an 83% score (which amounts to about a "B-" grade which is the typical average grade for the class). If you do better than expected of a good report, you will have points added to give a higher score.

Webb1. SO 3 and H 2 SO 4 (fuming) 2. 3. Sulfuric acid is needed in order for a good electrophile to form. Sulfuric acid protonates nitric acid to form the nitronium ion (water molecule is lost). The nitronium ion is a very good electrophile and is open to attack by benzene. Without sulfuric acid the reaction would not occur. 4. joseph schoeber casper wyWebb1. Source of nitronium ion- nitric acid is not a sufficient electrophile alone. But with sulfuric acid, it is strong enough. 2.
