Type of isomerism exhibited by compounds [ Cr ( H ₂ O )₆ ] Cl ₃, [ Cr ( H ₂ O )₅ Cl ^ Cl Cl ₂ H ₂ O , [ Cr ( H ₂ O )₄ Cl ₂ ] Cl ₂ . H ₂ O . and the value of coordination number ( CN ) of central metal ion in all these compounds, respectively is:
Options
- AIonisation isomerism, CN =4
- BSolvate isomerism, CN =6
- CGeometrical isomerism, CN =4
- DOptical isomerism, CN =4
Correct answer
B. Solvate isomerism, CN =6
Step-by-step solution
Solvate isomerism differ by whether or not a solvent molecule is directly bonded to the metal ion or merely present as free solvent molecules in the crystal lattice. - [ Cr ( H ₂ O )₆ ] Cl ₃, [ Cr ( H ₂ O )₅ ClICl ₂ . H ₂ O . and [ Cr ( H ₂ O )₄ Cl ₂ ] Cl ₂ 2 H ₂ O show solvate isomerism. - Co-ordination number of Cr =6
