Question

using VSEPR THEORY SHOW 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

Answer 1

1) BF4- has 4 electron pairs around the central boron atom, which gives it a tetrahedral shape.
2) SF3+ has 3 electron pairs around the central sulfur atom, which gives it a trigonal pyramidal shape.
3) ICI4- has 4 electron pairs around the central iodine atom, which gives it a square planar shape.
4) IF5 has 5 electron pairs around the central iodine atom, which gives it a square pyramidal shape.
5) PF5 has 5 electron pairs around the central phosphorus atom, which gives it a trigonal bipyramidal shape.
