Electrophilic aromatic substitution

layers in the test tube when concentrated sulphuric acid was added into cyclohexene. Explain the reason behind the reaction. Ans: The substances mix in the test tube when concentrated sulphuric acid was added into cyclohexene because they react by electrophilic addition to form alkyl hydrogen…

Introduction: Nitrous acid (HNO2) is used as a source of nitrosonium ion (N≡O+). The nitrosonium ion by reacting with an aromatic amine converted into a diazonium salt. As diazonium ion is a weak electrophile, it reacts with electron-rich, aromatic coupling agents to produce an azo dye. The products are mainly ortho and para due to the reaction being an electrophilic aromatic substitution Reaction: p-nitroaniline p-nitro benzenediazonium chloride Para-red…
