The reaction of ‘tert-butyl methyl ether’ with one equivalent of HI gives
  1. tert-butyl iodide and methyl iodide
  2. iso-butene and methyl iodide
  3. iso-butene and methanol
  4. tert-butyl iodide and methanol

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, $\mathrm{S}_{\mathrm{N}} 1$ mechanism followed. Iodine is attached to tertiary C-atom and $-\mathrm{OH}$ group is attached to methyl group.
