Question

using VSEPR THEORY explain why
1)BF4- is a tetrahedral molecule
2)SF3+ is a Trigonal pyramidal molecule
3)ICI4- IS A SQUARE PLANER molecule
4IF5 IS A SQUARE pyramidal molecule
5)PF5 IS A TRIGNAL BIPYRAMIDAl molecule help Dr bob222

Answer 1

I don't know what you want in the way of an explanation. You count the number of regions of high electron density. For BF4^-, that is 4 and since the groups bond to the central atom arrange themselves so they are as far apart as possible, then tetrahedral is the shape it takes.

Answer 2

yes that is what I wanted can you do this for every one Dr Bob 222 thanks
