A carbon atom and a hydrogen atom form a covalent bond in a molecule.
What is a Molecule?
A molecule is made up of two or more atoms, the two atoms can be the same or different.
There are mainly for types of bonds.
1. Covalent Bond
2. Ionic Bond
3. Metallic Bond
4. Hydrogen Bond
To form an ionic bond high electronegativity difference is needed.
The electronegativity of Carbon is 2.5 and,
The electronegativity of Hydrogen is 2.1
The difference between the electronegativity is 0.4, which is very small and so they form a nonpolar covalent bond.
Carbon forms a single bond with Hydrogen, methane CH₄.
Carbon also forms a double bond with Hydrogen, ethene C₂H₄.
and,
Carbon also forms a triple bond with Hydrogen, butyne C₄H₆.
The molecule formed by the atoms Carbon and Hydrogen is called Hydrocarbons.
Hydrocarbons have vast usage as fuels, to manufacture polymer chains, pharmaceuticals, etc.
