For the H–Cl bond the potential-energy minimum occurs at an internuclear distance of 127 pm. The H–F bond is known to be 16 pm shorter and has a bond energy that is 90 kJ mol⁻¹ larger than that of H–Cl. Determine (a) the approximate internuclear distance at the minimum of the H–F potential-energy curve and (b) whether the well you would sketch for H–F should be deeper or shallower than that of H–Cl.
