Question

Identify the product(s) is/are formed when 1-methoxy propane is heated with excess HI. Name the mechanism involved in the reaction.

Answer 1

\[\ce{\underset{1-methoxy propane}{CH3 - O - CH2 - CH2 - CH3} + HI -> \underset{\underset{(Iodomethane)}{Methyl Iodide}}{CH3I} + \underset{1-propane}{CH3 - CH2 - CH2 - OH} ->[HI] \underset{1-Iodopropane}{CH3 - CH2 - CH2 - I} + H2O}\]

Ethers having the primary alkyl group undergo an SN² reaction.
