A more electronegative atom/group prefers to occupy that hybrid orbital which has smaller percentage of s-character.(bents rule )How to find s-character in any hybridized orbital

Dear Student,
for instance take ‘sp’ hybridisation ..in this one s and one p is involved so percentage of s is 50%
in sp2 .. there is one s and two p .. so 1/3= 3.33%
similarly in sp3 .. one s and 3 p..so therefore 1/4= 25%
