16th group elements S, Se, Te and Po form different type of halides; the hexa, tetra, di and monohalides. The polarity of the M – F bond increases as the size of the atom M increases Tetrafluorides and tetrachlorides are formed by almost all elements while Te and Po form solid tetraiodides. Only sulphur forms the dihalide, SCl2
Lewis acid character of SCl4, SeCl4 and TeCl4 is in the order
(A) TeCl4 > SeCl4 > SCl4
(B) SCl4 > SeCl4 > TeCl4
(C) SeCl4 > SCl4 > TeCl4
(D) SCl4 > TeCl4 > SeCl4
