Hydrogen abstraction from the methyl group of methylbenzene (toluene) produces a radical called the _____ radical. A. allylic B. free C. halogen D. benzyllic The stability of benzyllic radicals can be explained by _____ theory. A. resonance B. bond order C. inductive D. molecular orbital 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 Which statement is true about ketones and aldehydes? A. Because alkyl groups are electron releasing, aldehydes are more reactive from both electronic and steric standpoints. B. Aldehydes have only one electron-releasing group to partially neutralize, and thereby stabilize, the positive charge at their carbonyl carbon atom. C. Ketones have 2 electron-releasing groups and are D. All are true.
