Introduction https://www.coursehero.com/file/26046948/Lab-3docx/ This study resource was shared via CourseHero.comFor an electrophilic aromatic substitution to occur, an electrophile and an aromat... ic compound are necessary. The electrophile is generated when the reaction is occurring. The electrophile will attach to a specific location on the aromatic; the location will depend on the substituents already on the substituents. On an aromatic group, there are electron- donating groups that are activating & increase reactivity. They are referred to as “ortho/para” directors. There are also electron-withdrawing groups that are deactivating & decrease reactivity. They are referred to as “meta” directors. In this experiment, a proton will be replaced with an electrophile (NO2+) on methyl benzoate, an aromatic ring. Materials element/compou nd properties structure hazards methyl benzoate/ C8H8O2 MW- 136.16 g/mol mp- -15°C  contact may slightly irritate skin, eyes and mucous membranes  may be slightly toxic by ingestion concentrated sulfuric acid/H2SO4 MW- 98.072 g/mol  corrosive to metals and tissue  will char wood and most other organic matter on contact  long term exposure to low concentrations or short term exposure to high concentrations can result in adverse health https://www.coursehero.com/file/26046948/Lab-3docx/ This study resource was sha [Show More]
