Question

5. All electron-donating groups are activating groups and all are ortho-para directors with the exception of substituents, all electron-withdrawing groups are deactivating groups and all are meta directors. A. hydroxyl B. amino C. halogens D. alkoxyl 6. Hydrogen abstraction from the methyl group of methylbenzene (toluene) produces a radical called the radical. A. allylic B. free C. halogen D. benzyllic 7. The stability of benzyllic radicals can be explained by theory. A. resonance B. bond order C. inductive D. molecular orbital 8. In aldehydes, where one group is a hydrogen atom, the central carbon of the tetrahedral product formed from the aldehyde is less crowded and the product is less stable. A. True B. False

Answer 1

UREAU ESPAIS halogens are deactivating groups But ontho para director so ef is exception. A on Activating ontho/para (B) TNH2 Activating ortho para © -či: + deactivating - ortho para (D2 -ÖR → Activating - Orthopara I so option (C) is correct TOT H₂o H2 (benzylic Radical option (o) is correct because this radical Connect with benzene. Resonane so option (4) is correct so this is (true) land crowded)

Please give thumb up.
