Question

What atomic or hybrid orbital on the central as atom makes up the sigma bond between this as and an outer f atom in hexafluoroarsenate ion, asf6- ?

Answer 1

The sigma bond between the central As atom and the outer F atom in hexafluoroarsenate ion is formed by the overlap of an sp³ d² hybrid orbital on the central As atom and an atomic orbital on the outer F atom.

Step-by-step explanation:

The sigma bond between the central As atom and the outer F atom in hexafluoroarsenate ion (AsF6-) is formed by the overlap of an sp³ d² hybrid orbital on the central As atom and an atomic orbital on the outer F atom.
