Question

Which one of the following has
the highest dipole moment CS2 cl2 chcl3 ccl4

Answer 1

Answer: ChCl3

Explanation :

DIpole moment is a vector quantity which depends on polarity of a molecule.

in CS2 - the molecule is linear shaped and dipole moments cancel each other due to vector addition and hence it is zero.

In cl2 - the molecule is non polar as the electronegativity is same for both Cl.

In CCl4, the tetrahedral shaped molecule is such that, the dipole moments cancel out each other and hence no net dipole moment.

In ChCl3 - Due to the presence of a hydrogen, there is a net dipole moment.
