Question

Predict which out of the following molecules will have higher diple moment and why ?
`CS_(2) and OCS`

Answer 1

`Soverset(larr)=Coverset(rarr)(=S)and Ooverset(larr)=Coverset(rarr)(=S)` , bond are linear molecules but bond moments in `CS_(2)` cancel out so that net
dipole moment = 0 . But in OCS, bond moment of C = O is not equal to that of C = S . Hence , it has a net
dipole moment. Thus , dipole moment of OCS is higher.
