This theory provides electron counting rules to predict the structure of clusters. It is formulated by Wade hence it is called as Wade’s rule. According to Wades rule the total skeletal 〖 𝑒〗^−s of Boranes or Carboranes are calculated as follows; In a Carboranes or Boranes a CH unit is contributes 3 〖 𝑒〗^−s A BH unit is contributes 2〖 𝑒〗^−s and BHB unit contributes 1 〖 𝑒〗^−s In Boranes a BH unit is Isolable with CH unit. Hence, a CH unit substitute BH unit from the Boranes it give rise to Carboranes. Each –ve charge which is present on coordination sphere adds to 〖 1𝑒〗^−s. H  1 〖 𝑒〗^−s , C  4 〖 𝑒〗^−s ,P  5〖 𝑒〗^−s If we add above all the 〖 𝑒〗^−s then we get total number of skeletal 〖 𝑒〗^−s . If it is divided by 2 then we get total number of skeletal e(-) pairs. #ugcnet #doorsteptutor #examrace
