Of the two molecules OCS and CS_(2) which one has higher dipole moment value ? Why ? |
Answer» Solution :OCSand `CS_(2)` :  The dipole moment `H_("OCS") = 0.7149 pm 0.0003 " Debye " CS_(2) : S = C = S` In `CS_(2)`the bond dipole of 2C = S have same values and bond dipoles cancel each ether so dipoles moment of `CS_(2)` is zero . Among OCS and `CS_(2)` OCS has a HIGHER DIPOLEMOMENT because in OCS oxygen is more ELECTRONEGATIVE that sulphur and C = S and C = O bond in OCS molecules do not cancel each other. On other hand `CS_(2)` due to linear STRUCTURE the bond dipole to two `C = S` bonds cancel each other. On the other hand `CS_(2)` due to linear structure the bond dipoles of two C = S bonds cancel each other and the result and dipole moment value is zero . So OCS has a higher dipole moment than `CS_(2)`. |
