The formula for the complex, dichlorobis (urea) copper (II) is

1. [Cu{O=C(NH2)2}Cl2]
2. [Cu{O=C(NH2)2}2]Cl2
3. [CuCl2{O=C(NH2)2}2]
4. [CuCl2]{O=C(NH2)2}2

Correct answer: [CuCl2{O=C(NH2)2}2]

Solution

The correct formula is [CuCl2{O=C(NH2)2}2] because the copper(II) ion is coordinated with two urea molecules and two chloride ions in the complex.
