$(i)$ and $(iv)$

Vedclass · Answer

(A) $CO_2$ is a linear molecule with symmetric charge distribution,so its net dipole moment is zero.$COCl_2$ (phosgene) has a trigonal planar geometry but the bond dipoles do not cancel out due to different electronegativities of $O$ and $Cl$ atoms,so it has a non-zero dipole moment.$CH_2Cl_2$ (dichloromethane) is tetrahedral and asymmetric,resulting in a non-zero net dipole moment.$BCl_3$ is a trigonal planar molecule with symmetric charge distribution,so its net dipole moment is zero.Therefore,the species with zero dipole moment are $(i)$ and $(iv)$.

The correct set of species with zero dipole moment is:
$(i) \, CO_2, \, (ii) \, COCl_2, \, (iii) \, CH_2Cl_2, \, (iv) \, BCl_3$
