Question

Which of the following is true about COS.

1.COS has no dipole moment because the molecule is linear anddipole moments cancel in linear molecules.

2.COS has a dipole moment because it is asymmetric and the dipolemoments do not completely cancel.

3.COS has a dipole moment because the molecule is bent and thedipole moments combine.

4.COS has no dipole moment because it is bent and the dipolemoments cancel

5.COS has no dipole moment because its bonds are all non polar.
