Question

true/false:

1. the major product when p-ethylbenzoic acid is treated with a mixture of concentrated nitric and sulfuric acids will be 4-ethyl-3-nitro-benzoic acid.

7.-10. multiple choice is pictured below

Multiple Choice 7. Which of the following will react with Cl2/AlCl3 at the fastest rate? Benzoic acid B. toluene C. bromobenzene D. anisole 8. Which of the following reagents will reduce p- nitrotoluene to p-methylaniline? A. W-K. B. H2Cr04 C. H2, Ni D. NBS, light 9. Which of the reagents in #8 will convert p- nitrotoluene to p-nitrobenzyl bromide? 10. Which reagent in #8 will convert p-nitrotoluene top- nitrobenzoic acid?

Answer 1

Answer I CooH COOH Conc HNO3 H₂SO4 NO2 CH₂CH3 CH2 CH3 p-ethylbenzoic acid 4-ethyl-3-nitrobenzoic acid Therefore the given statement is true Answer 7 Br L. OCH3 COOH benzene Ring. through resonance Hyperconjugation. [but - I effect Benzoic Acid Toluene Bromobenzene Anisole Deactivates the Activates the Activates the Activates the tengene ring Benzene ring I benzene ring through through resonance hyperconjugation & dominates. Therefore Anisole reacts with Clz / Al(ds at the faster rate through electrophilic substitution reaction . Correct option (d) Anisole. Answer 8 CH3 Hz, Ni High Pressure. NO20 Correct option - (C) Hz, Ni CH3 NH2

Answer q CH2B8 NBS NO2 NO2 (free radical mechanism) N Correct option & (D) NBS, light Answer to CooH CH3 H2 Croy NO2 NO2 H2Crou is an oxidizing agent. It will oxidise - CH3 group on benzene to - cooh. Correct option : (6) H2Cro4
