The nitration of methylbenzene
WebNitration of methylbenzene. This gives a mixture of isomers which can be separated by a series of crystallisation and distillation steps. On cooling the reaction mixture, most of the … Webpossible when reaction on substituted benzenes occur, the isomers include ortho, meta, and para. Nitration at the meta position is optimal because of the partial charges residing at the ortho and para positions to repel the positively charged nitronium ion. Experimental Procedure: 6 mL of concentrated sulfuric acid was transferred into a 125-mL Erlenmeyer …
