The strongest type of covalent bond.
Explanation:
Sigma bonds form via the "head on" overlapping of atomic orbitals of the component atoms, so
Single bonds are typically sigma only, whilst double/triple bonds contain a mixture of sigma and pi bonding. But sigma is the only type that is "head to head" direct overlapping of electron orbitals, which makes them stronger.
