Radical bromination of cyclohexene using NBS gives 3-bromo-1-cyclohexene. Draw the allylic radical intermediate formed during this reaction, showing both resonance structures

An unknown compound is treated with HBr in the dark. The product of this reaction is reacted with potassium t- butoxide. The product of reaction 2 is treated with HBr and peroxide. In reaction 4 the product of reaction 3 is treated with lithium acetylenide (C2H"). The product of reaction4 is reduced with hydrogen using platinum as a catalyst. This final product was determined to be n-pentylcyclopentane. What is the name of the original unknown compound? ABC T T T Arial 3 (12pt) Path: p Words:0
