Question

Give one example each of molecules with

{sp}^{2}

and

{sp}^{3}

hybridization.

Accepted Answer

Ammonia is an example of ${sp}^{3}$ hybridisation.

The electronic configuration of nitrogen Is $1 s^{2} 2 s^{1} 2 p_{x}^{1} 2 p_{y}^{1} 2 p_{z}^{1}$ . Here, the central atom, nitrogen shows ${sp}^{3} -$ hybridisation and forms four ${sp}^{3} -$ hybrid orbitals. Each of the three half-filled ${sp}^{3}$ -hybrid orbitals overlaps with $1 s$ -orbital of a hydrogen atom to form sigma bonds. A pair of electrons are present in the fourth ${sp}^{3}$ -orbital. Here, due to Ione pair-bond pair repulsion, according to VSEPR theory, the regular tetrahedral geometry is distorted. The shape of ${NH}_{3}$ molecule becomes pyramidal and the bond angle is reduced to $107^{0}$ .

An example of ${sp}^{2} -$ hybridisation is ${BCl}_{3}$ .

The ${sp}^{2} -$ hybrid orbitals of the boron atom are directed in space making an angle of $120^{0}$ with each other. Each hybrid orbital contains one half-filled electron. Now three $3 p -$ orbitals of chlorine with one electron in each overlap with three ${sp}^{2} -$ hybrid orbitals of boron, separately. As a result, three sigma bonds are formed. Therefore, the shape of ${BCl}_{3}$ is trigonal and the bond angle is $120^{0}$ .
