Introduction – Covalent Molecules:
In Covalent Molecules, atoms combine by sharing electrons.
Covalent molecules have a definite shape due to the fact that Covalent bonds are rigid and highly directional. However, the Ionic bondsAn electrovalent or ionic bond is formed when a metal atom transfers one or more electrons to a non-metal atom. Ionic or electrovalent compounds are those compounds which are formed by... More are not directional. Shapes of Covalent molecules are as follows:
1. Linear Shape:
All diatomic molecules are Linear in shape e.g. H2, Cl2, O2, N2. Other Compounds that have a Linear shape are CO, HCl, HF, CO2, SO2, etc. A linear molecule is a molecule in which atoms are deployed in a straight line, and the bond angle is 180°C.
The Linear shape of Hydrogen, Oxygen, Nitrogen, and Chloride:
(a) Hydrogen (H2)
(b) Oxygen (O2)
