Facts and details about the nitration of benzene and methylbenzene the nitration of benzene methyl groups are said to be 2,4-directing. For the first reaction, the nitration of methyl benzoate, a yield of 7832 g was achieved and based on melt point analysis, the chemical was likely to be m-nitrobenzoate although an ester is a deactivating compound, the reaction appeared to proceed reasonably well, with a good overall yield.
The methyl benzoate and acetanilide react with hno3, h2so4, and glacial acetic acid i think there would be two different products, but i'm not sure how to name them (one is the methyl benzoate with a nitrile group on carbon 3 the other is acetanilide with a nitrile on carbon 4) i also have no idea how to tell which product would form, please explain so i can understand this for the exam. Electrophilic aromatic substitution: nitration of methyl benzoate benzene rings are components of many important natural products and other useful organic compounds therefore, the ability to put substituents on a benzene ring, at specific positions relative to each other, is a very. 2 procedure – nitration of acetanilide place 65 g of acetanilide in a 125-ml erlenmeyer flask, add 10 ml of glacial acetic acid (caution: strong irritant), and warm the flask on a steam bath until the acetanilide dissolves.
