where n is the number of bonds taken into account, [alpha] is an empirical constant chosen to give HOMA = 0 for a nonaromatic system and HOMA =1 for a system with all bonds equal to the optimal value [R.sub.opt], and [R.sub.i] is the individual bond length [30].
Besides the electronegativity, an increase of the C-halogen bond length was also observed when the atomic radius of halogen atom augmented regardless of the media: in water, the C-halogen bond lengths were 1.352 [Angstrom] (C-F), 1.746 [Angstrom] (C- Cl), and 1.846 A (C-Br).
As can be seen in Figure 1(a), the bond lengths of C1-C2 and C1-C1 have the same value 1.44 [Angstrom] due to the symmetric structure, while the bond length of C1-C4 is 1.41 [Angstrom], which is relatively smaller than that of C1-C2.
