The correct options are
B Copper(II) chloride
C Cupric chloride
∙ In CuCl2 the valency of copper is two and that of chlorine is one.
∙ Copper shows variable valencies of one and two.
∙ When an atom shows two valencies, its name ends with-'-ous' for lower valency, with '-ic' for higher one
∙ Thus, copper exhibiting lower valency is known as cuprous and with higher valency is known as cupric.
∙ Hence, the name of the compound CuCl2 is copper(II) chloride or cupric chloride.
