Solution

Share

Let us analyze each molecule for polarity:

- $$CCl_4$$: Tetrahedral, symmetric, dipole moments cancel. Non-polar.

- $$CO_2$$: Linear, symmetric, dipole moments cancel. Non-polar.

- $$CH_2=CH_2$$: Planar, symmetric. Non-polar.

- $$CHCl_3$$: Tetrahedral but asymmetric (one H, three Cl). Net dipole moment exists. Polar.

The answer is $$CHCl_3$$, which corresponds to Option (4).
