1.	Predict which out of the following molecules will have higher diple moment and why ? CS_(2) and OCS
Answer» Solution :`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 MOMENTOF C = O is not equal to that of C = S . Hence , it has a net dipole moment. THUS , dipole moment of OCS is higher.
