Question

Which of the following molecules does not possess a permanent dipole moment :
(1) H2S
(2) SO2
(3) S(O3)2-
(4) CS2

Answer 1

CS2..It's nonpolar. The shape is linear. There is no difference in one side of the molecule than the other. CS2 looks like S=C=S, it has a center of symmetry on the carbon and thus can have no polarity...so option 4
