What is Wrong?
Select the keyword or phrase that will best complete each sentence. Key terms: A radical is a reactive intermediate with a single unpaired electron, formed by homoloysis of a covalent bond. paired unpaired Allylic radicals are stabilized by resonance, making them more stable than tertiary radicals increases inductive effects A compound that contains an especially weak bond that serves as a source of radicals is called a radical initiator ess homoloysis decreases more J Treatment of cyclohexene...

Any explanations would be greatly appreciated. This wasn't covered
very well so I'm trying to understand it.

Your answer is partially correct. Try again Although both 1-bromobutane and 4-bromo-1-butene are primary halides, the latter undergoes elimination more rapidly. How can this behavior be explained? but-2-ene The product formed when 1-bromobutane undergoes elimination is a simple monosubstituted alkene J. when 4-bromo-1-butene undergoes elimination, the product is relative stablites of the products. Since but-1,3-ene a conjugated dieneand therefore, a more stable # product. The transition states leading to the products reflect the the transition state leading to 1,3-butadiene has...
