Ethylene chloride is a _______ halide

The main difference between geminal dihalide and vicinal dihalides is that geminal dihalides have both halide groups attached to the same carbon atom of the compound whereas vicinal dihalides have two halide groups which are attached to two adjacent carbon atoms in the same compound.

Ethylene chloride is a vicinal dihalide and its chemical formula is $\mathrm{Cl}-\mathrm{C}{\mathrm{H}}_2-\mathrm{C}{\mathrm{H}}_2-\mathrm{Cl}.$
