The reaction of ‘tert-butyl methyl ether’ with one equivalent of HI gives

Options

  1. Atert-butyl iodide and methyl iodide
  2. Biso-butene and methyl iodide
  3. Ciso-butene and methanol
  4. Dtert-butyl iodide and methanol

Correct answer

D. tert-butyl iodide and methanol

Step-by-step solution

When tert-butyl methyl ether reacts with HI, it will formed tert-butyl iodide and methanol. Since, the tertiary carbocation forms which is stable. So, S _ N 1 mechanism followed. Iodine is attached to tertiary C-atom and - OH group is attached to methyl group.
