Of the two molecules OCS and CS_(2) which one has higher dipole moment value .Why? |
Answer» Solution :OCS and `CS_(2)`:  The DIPOLE moment `mu_(ocs) = 0. 7149 + 0. 0003` Debye. `Cs_(2):`S = C = S In `CS_(2),` the bond dipoles of 2 C = S have same values and bond dipoles cancel each other so dipole moment of `CS_(2)` is zero. Among OCS and `CS_(2),` OCS has a HIGHER dipole moment because in OCS OXYGEN is more electronegative than sulphur and C =S and C = O bonds in OCS molecules do not cancel each other. On the other HAND `CS_(2)` due to linear structure, the bond dipole of twoC = 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 RESULTANT dipole moment value is zero. So OCS has a higher dipole moment than `CS_(2)`. |
