Question

The geometry of a complex species can be understood from the knowledge of type of hybridisation of orbitals of central atom. The hybridisation of orbitals of central atom in [Be(OH)4] and the geometry of the complex are respectively.

Options

  • sp3, tetrahedral

  • sp3, square planar

  • sp3d2, octahedral

  • dsp2, square planar

Solution

sp3, tetrahedral

Explanation:

Boron has die electronic configuration: 1s2 2s2 2px1 2p0 y 2p0z

In the excited state, 2s-orbital electrons are impaired and one electron is shifted to a p-orbital. Now, hybridisation occurs between one s-and three p-orbitals to give sp3 hybridisation and tetrahedral geometry.
