5. Identify the product.

6. Arene B (C10H14) has 5 possible mono chloro derivatives (C10H13Cl) considering both ring and silde chain halogenation vigorous oxidation of B yields an acidic compound C8H6O4 having only one mononitro substitution product C8H5O4NO2. Identify B and also draw structure of 5 monochloro derivatives. 7. When alkyl halides are treated with aqueous AgNO3, silver halide precipitate and an alcohol is formed. From what you know about the SNI reaction, propose a mechanism for the following conversion.
