What molecule has a single bond

The chemical bond between the two atoms with two valence electrons in Chemistry is a single bond. That is, there is a bond between the atoms and a single pair of electrons. A single connection is therefore a type of covalent connection.

In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons. That is, the atoms share one pair of electrons where the bond forms. Therefore, a single bond is a type of covalent bond.
