In a single bond, which type of bond is formed?

covalent pi delta sigma

Correct Answer:

sigma

Explanation:

In a single covalent bond, the bonding interaction is a sigma bond formed by end-to-end overlap of atomic orbitals along the line between the two nuclei. This head-to-head overlap concentrates electron density directly between the atoms, creating the strongest, simplest bond that holds them together for a single bond. In contrast, pi bonds arise from sideways overlap of p orbitals and occur in double and triple bonds, adding strength beyond the sigma bond but not forming the single bond itself. Delta bonds involve more exotic, typically d-orbital interactions and aren’t what constitutes a typical single bond. So, the bond type that forms in a single bond is the sigma bond.
