Q87 · Chemistry

Consider the following reaction :

C6H5−CH2−O−C6H5→ΔHIA+B\mathrm{C_6H_5-CH_2-O-C_6H_5 \xrightarrow[\Delta]{HI} A + B} (benzyl phenyl ether)

Identify products A and B.

The figure, described in words

Benzene rings drawn as structures in the reactant and all options (benzyl phenyl ether; toluene, iodobenzene, phenol, benzyl alcohol, benzyl iodide).

  1. 1A = C6H5CH3\mathrm{C_6H_5CH_3} and B = C6H5I\mathrm{C_6H_5I}
  2. 2A = C6H5CH3\mathrm{C_6H_5CH_3} and B = C6H5OH\mathrm{C_6H_5OH}
  3. 3A = C6H5CH2OH\mathrm{C_6H_5CH_2OH} and B = C6H5I\mathrm{C_6H_5I}
  4. 4A = C6H5CH2I\mathrm{C_6H_5CH_2I} and B = C6H5OH\mathrm{C_6H_5OH}Official answer
