d = r₁ + r₂ + correction
d = 0.77 + 0.77 + (0.000)
d = 1.540 Å

About Bond Length

Bond length is the equilibrium distance between the nuclei of two bonded atoms. It can be estimated by adding the covalent radii of the atoms involved. Multiple bonds (double, triple) are shorter than single bonds due to increased electron density between the nuclei. Bond length is inversely related to bond strength and bond order.
