Q95 · Chemistry

Identify compound X in the following sequence of reactions :

C6H5CH3\mathrm{C_6H_5CH_3} →Cl2/hν\xrightarrow{\mathrm{Cl_2}/h\nu} X →373 KH2O\xrightarrow[\text{373 K}]{\mathrm{H_2O}} C6H5CHO\mathrm{C_6H_5CHO}

The figure, described in words

Reaction scheme and all four options drawn as benzene-ring structures: C6H5CH3 -> X (Cl2/hv) -> C6H5CHO (H2O, 373 K); options are Ph-Cl, Ph-CH2Cl, Ph-CHCl2, Ph-CCl3.
