Question

Which of the following is true about the complexes $\left[Cu\right(C{H}_{3}C{H}_{2}N{H}_2{)}_4{]}^{2+}S{O}_4^{2-}$ and $\left[Ag\right(C{H}_{3}C{H}_{2}N{H}_2{)}_2{]}^{+}C{l}^{-}$:

• A. Both complexes $\left[Cu\right(C{H}_{3}C{H}_{2}N{H}_2{)}_4{]}^{2+}S{O}_4^{2-}$ and $\left[Ag\right(C{H}_{3}C{H}_{2}N{H}_2{)}_2{]}^{+}C{l}^{-}$ contain a coordinate bond.
• B. The complex $\left[Cu\right(C{H}_{3}C{H}_{2}N{H}_2{)}_4{]}^{2+}S{O}_4^{2-}$ contains coordinate bond. But no coordinate bond is present in the complex $\left[Ag\right(C{H}_{3}C{H}_{2}N{H}_2{)}_2{]}^{+}C{l}^{-}$
• C. Neither $\left[Cu\right(C{H}_{3}C{H}_{2}N{H}_2{)}_4{]}^{2+}S{O}_4^{2-}$ nor $\left[Ag\right(C{H}_{3}C{H}_{2}N{H}_2{)}_2{]}^{+}C{l}^{-}$ contain a coordinate bond.
• D. The complex $\left[Ag\right(C{H}_{3}C{H}_{2}N{H}_2{)}_2{]}^{+}C{l}^{-}$ contains coordinate bond. But no coordinate bond is present in the complex $\left[Cu\right(C{H}_{3}C{H}_{2}N{H}_2{)}_4{]}^{2+}S{O}_4^{2-}$

Answer 1

The correct option is A Both complexes $\left[Cu\right(C{H}_{3}C{H}_{2}N{H}_2{)}_4{]}^{2+}S{O}_4^{2-}$ and $\left[Ag\right(C{H}_{3}C{H}_{2}N{H}_2{)}_2{]}^{+}C{l}^{-}$ contain a coordinate bond.
