\[\begin{split} \Delta &= 428 - \sqrt{432 \times 239} \\ &= 106.6\; kJ\; mol^{-1} \\ &= 25.48\; kcal\; mol^{-1} \end{split}\]
\[\chi_{Cl} - \chi_{H} = 0.208 \times \sqrt{25.48},\]
\[\chi_{Cl} = 2.1 + 1.05 = 3.15\]

In a \(\sigma\) bond, a bonding orbital is a centrosymmetric g orbital, whereas an antibonding orbital is a non-centrosymmetric u orbital.
