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...
