Do you struggle to predict the structure of metal carbonyls using cluster electron counting? This video explains the application of the Wade-Mingo rule to inorganic clusters, detailing how to determine the skeletal electron pair count and correlate it to closo, nido, and arachno geometries. We break down the complex symmetry and electron distribution requirements necessary for competitive chemistry examinations.

(3 pairs of 𝒆^− s from the metal to ligand through back bonding + 3 pairs of 𝒆^−s from 3 carbonyls through σ –bonds). These are non-skeletal s when these non-skeletal 𝒆^− s are subtracted from the TEC (Total Electron Count) gives the total skeletal 𝒆^− s. By dividing with 2 it gives the total number of skeletal 𝒆^− pairs. The High Nuclear carbonyl Clusters are 𝒆^− s deficient these structures have polyhedron structure. The polyhedron structures of HNCC are related with Wades rule. These rules shows the relationship between total 𝒆^− s count and structure of various CO cluster. According to these rules a polyhedron closed structure obeys total 𝒆^− count as follows; #ugcnet #doorsteptutor #examrace
