This abnormal change in orientation among benzofuran and thionaphthene is related to the electronegativity of oxygen and sulphur. Due to the fact oxygen is more electronegative than sulphur, the unshared electrons all-around oxygen are held much more tightly than All those of sulphur. As a result, the strongly electronegative character of oxygen cuts down the extent to which an unshared pair interacts Along with the two double bonds to type the aromatic method. Hence, benzofuran behaves to a considerable extent like an olefin. Resulting from this distortion of electrons, ionic construction eighteen is of larger great importance in benzofuran (Fig. three) and As a result electrophilic substitution with the C-2 posture is favored. However, in thionaphthene, the electronegativity of sulphur is secondary into the stabilizing impact of benzene resonance, as well as ionic construction 20 which has a adverse cost in the C-two position is of larger great importance (Fig. four).fifty four
