Answer to Question #5338 in Inorganic Chemistry for Jun Wang

Question

what is the hybridization of Se :
1. Li and Se (Li20)
2. Se and O (SeO)

hey, my answer for this is SP3 , and sp2, and it was wrong !

Answer 1

For SeO it is sp³,cause Se are both sp³ hybridized, because they are tetrahedrons, therefore comprising of four hybrid orbitals (3 p's, 1 s (sp³)).
and for Li₂Se I think it is sp³d³
