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

4. When 1-iodo-1-methylcyclohexane is treated with sodium ethoxide, the more highly substituted alkene product predominates. Alternatively, when potassium tert-butoxide is used as a base, the less substitute alkene predominates. Give the structures of the two bases, and the two products and explain the difference in regioselectivity. 5. Draw the diastereomer of the compound shown below. Explain which chair conformation one will react faster in the presence of a strong base to give a substituted cyclohexene. (Draw the chair structure of...

Was a methyl shift done here because the OH couldn't be placed
on the more substituted carbon and do you proceed by always doing
methyl shifts if this happens? Would you be so kind and including
hydrogens in the reaction mechanism. Thank you !! final in a couple
of hours.
