Question

Which of the following complexes is reluctant to dehydration?

• A. $\left[Cr\right(H_{2}O{)}_{5}Cl]C{l}_2.H_{2}O$
• B. $\left[Cr\right(H_{2}O{)}_{4}C{l}_2]Cl.2H_{2}O$
• C. $\left[Cr\right(H_{2}O{)}_6]C{l}_3$
• D. All of these

Answer 1

The correct option is C $\left[Cr\right(H_{2}O{)}_6]C{l}_3$

A complex in which the $H_{2}O$ molecules are inside the coordination sphere are reluctant to dehydration.
