Which hubrid orbitals surround the central atom in the compound aluminum triflouride?also what is the shape of silicon tetrafluoride?how do you do this problem?help!
For silicon tetrafluoride, if you draw the lewis dot diagram, you will find that silicon will have 4 valence electron and fluoride with 7 valence electron eachSo you end up with total valence electron of 32When filling in all the electrons of the diagram below, you will use up all 32, so the shape is tetrahedral(((F ))) | F-Si-F ))) | (((F For aluminum trifluoride, first of all, it is an ionic compound by most definitions and would exhibit crystalline structureBut if we could isolate 1 AlF3 molecule, we will find that there are three fluoride around the central atom of Al, so the hybridization should be sp2.
