Question

which of the following 2 molecules have higher dipole movement and why....

1) OCS

2) CS2

Answer 1

The dipole moment of CS2 is zero due to its regular geometry. {S=C=S}
It is linear, due to sp hybridisation.

In OCS, O has higher electronegativity than sulphur. Hence they are unequal and a dipole moment exists. {O=C=S}
Hence OCS has higher dipole moment.
