Solution
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) | \[\ce{\underset{thiocyanato}{M<-SCN}}\] | \[\ce{\underset{isothiocyanato}{M<-NCS}}\] |
