उत्तर
Linkage isomerism
Examples:
| (i) | \[\begin{array}{cc} \phantom{.........}\ce{O}\\ \phantom{.......}/\\ \ce{M <- N}\phantom{....}\\ \phantom{.......}\backslash\backslash\\ \phantom{.........}\ce{O}\\ \ce{nitrito-N} \end{array}\] |
\[\ce{\underset{nitrito — O}{M<-O-N=O}}\] |
| (ii) | \[\ce{\underset{thiocyanato}{M<-SCN}}\] | \[\ce{\underset{isothiocyanato}{M<-NCS}}\] |

Assertion: Linkage isomerism arises in coordination compounds containing ambidentate ligand.
Reason: Ambidentate ligand has two different donor atoms
CoSO4Cl.5NH3 exists in two isomeric forms ‘A’ and ‘B’. Isomer ‘A’ reacts with AgNO3 to give white precipitate, but does not react with BaCl2. Isomer ‘B’ gives white precipitate with BaCl2 but does not react with AgNO3. Answer the following questions.
- Identify ‘A’ and ‘B’ and write their structural formulas.
- Name the type of isomerism involved.
- Give the IUPAC name of ‘A’ and ‘B’.
