(a)
Interpretation:
The hybridization of the central atom of the molecules with the following molecular geometries has to be predicted.
- (a) Tetrahedral (b) trigonal planar (c) trigonal bipyramidal (d) linear (e) octahedral
Concept Introduction:
Hybridization is a hypothetical concept. It refers to overlapping of atomic orbitals and the resultant orbitals formed are known as hybrid orbitals. An orbital that doesn’t involve in hybridization is termed as unhybridized orbital. After hybridization, the orbitals cannot be distinguished individually. The orientation of the orbitals while overlapping impacts the nature of the bond forms. By knowing the hybridization of central atom in the molecule its geometry can be predicted and vice-versa.
