How to calculate hybridisation of a compound ? What is the formula to determine the hybridisation of compound say C2H6, C2H4 , C2H2 Share with your friends Share 0 Vartika Jain answered this Dear Student, Hybridisation can be calculated using the formulaNo. of hybrid orbitals=12[No. of electrons in the valence shell of central atom(A)+No. of monovalent atoms (B) around A- Charge on cation (C)+Charge on anion (D)]or, H=12[A+B-C+D]if, H=2 then sp hybridisationH=3 then sp2 hybridisationH=4 then sp3 hybridisationH=5 then sp3d hybridisationH=6 then sp3d2 hybridisationFor calculating hybridisation in compounds like C2H6, etc.Use the given formulaH= No. of b.p+No. of l.pIn C2H6No. of b.p (for one C)=4No. of l.p=0Therefore, H=4=sp3 hybridisationIn C2H4No. of b.p (for one C)=3No. of l.p=0Therefore, H=3=sp2 hybridisation In C2H2No. of b.p (for one C)=2No. of l.p=0Therefore, H=2=sp hybridisationOnly σ electrons are counted. 1 View Full Answer
