Question

The shape of SO₄²⁻ ion is
(a) square planar (b) tetrahedral
(c) trigonal bipyramidal (d) hexagonal

Answer 1

Answer:

trignal bipyramidal (d) hexagonal

Answer 2

Tetrahedral is the shape of sulphate ion.

Explanation:

• Sulphate ion is the maximum oxidised state of sulphur where the oxidation state of sulphur is +6.

• Sulphate has two oxygen atoms which are directly bonded to sulphur by means of double bonds.

• The other two atoms of oxygen are bonded with sulphur by means of single bonds.

• The hybridization of sulphur in sulphate is sp3.

• So three p orbitals and one s orbital of sulphur hybridises to form 4 sp3 hybrid orbitals.

• The hybrid orbitals are at the angle of 104.8 °s to each other, which forms tetrahedral structure.
