Question

Few isomers are given below, Mark the correct statement regarding them.

(i) $\lbrack Cr(H_{2}O)_{6}\rbrack Cl_{3}$

(ii) $\lbrack Cr(H_{2}O)_{5}Cl\rbrack Cl_{2},H_{2}O$

(iii) $\lbrack Cr(H_{2}O)_{4}Cl_{2}\rbrack Cl.2H_{2}O$

• A. (i),(ii) and (iii) are hydrate isomers.
• B. (i), (ii) and (iii) are coordination isomers.
• C. (i), (ii) and (iii) are ionization isomers.
• D. (i) and (ii) are stereoisomers.

Answer 1

Answer: (A)

(i),(ii) and (iii) are hydrate isomers.

Answer 2

When different number of water molecules are present inside and outside the coordinations sphere, the isomersa are known as hydrate isomers or solvate isomers.
