The compound below is treated with N-bromosuccinimide (NBS) in the presence of light. Draw both resonance structures for the radical produced by reaction of the compound with a bromine atom. Assume reaction occurs only at the weakest C-H bond. • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Separate resonance structures using the symbol from the drop-down menu. • Include all valence radical electrons in your answer. 1.) The compound...

When 1-iodo-1-methylcyclohexane is treated with NaOCH2CH3, the more highly substituted alkene product predominates. When KOC(CH3)3 is used instead, the less highly substituted alkene product predominates. Please explain. A) Methylenecyclohexane is more stable than 1-methylcyclohexene B) The bulky iodo group is attacked mor readily by less bulky NaOCH2CH3 C) KOC(CH3)3 attacks the primary hydrogen, but NaOCH2CH3 attacks the secondary hydrogen D) 1-iodo-1-methylcyclohexane exists only in the chair conformation E) None of the above

Option #1: Given a source of Brą and bromine radicals (Br.), write TWO likely propagation steps for the bromination of: Option #2: Draw TWO likely resonance structures for the product that results when a bromine radical (Br.) abstracts H from this compound: Option #3: In 1839, Eduard Simon discovered styrene. He noticed that merely on exposure to heat, light, or air, it would become rubbery. Why is this reaction so easy? 41
