Bond Dissociation Energies of Common Alkanes

Alkanes are organic compounds that have only singly bonded carbon to carbon atoms. For example – Methane, Ethane is Alkanes as these only have carbon atoms linked with each other via single bonds.
In this article, I’ve put together Bond Dissociation Energies of some bonds in well-known Alkanes. Just on a side note – Bond Dissociation Energy is the amount of energy needed for breaking up a bond.
