Question 6 - 10 pts. Homework • Unanswered When (cis)-1-bromo-2-methylcyclohexane is treated with methanol and heat, four different products are formed -- two by substitution (1-methoxy-2- methylcyclohexane and 1-methoxy-1-methylcyclohexane) and two by elimination (1-methylcyclohexene and methylidene cyclohexane (you will have to look that one up!)). What conditions could be used to change the outcome of this reaction by promoting the production of 3-methylcyclohexene as the product? [] Fulls

(a) When cis-1-bromo-2-methylcyclohexane undergoes an E2 reaction, two products (cycloalkenes) are formed. What are these two cycloalkenes, and which would you expect to be the major product? Write conformational structures showing how each is formed. (b) When trans-1-bromo-2-methylcyclohexane reacts in an E2 reaction, only one cyclo- alkene is formed. What is this product? Write conformational structures showing why it is the only product.
