Question

What hybridization in [crf6-3] ?

Answer 1

My textbook says that [CrF6]3− is an example of sp3d2 hybridization. But I don't really see how. Chromium has an electronic configuration of:

3d:↑↑↑↑↑ 4s:↑

Give three more electrons and it might look something like this:

3d:↑↓↑↓↑↑↑ 4s:↑↓

This is the ground state of the electrons

Answer 2

Answer:

Explanation: Fluorine has -1 charge and since there are 6 F then their charge is -6. Net charge is -3 hence charge on chromium is +3. Now find out.
