Vedclass · Answer

(B) molecule has a permanent dipole moment if it is polar,meaning the vector sum of its individual bond dipoles is non-zero.$CO_2$ is a linear molecule with a symmetric structure,so its bond dipoles cancel out,resulting in a net dipole moment of $0$.$SiF_4$ has a tetrahedral geometry,which is highly symmetric,leading to a net dipole moment of $0$.$NO_2$ is a bent molecule due to the presence of an unpaired electron on the nitrogen atom,which results in a non-zero net dipole moment.$O_3$ (ozone) is also a bent molecule with a non-zero net dipole moment due to its angular structure.Therefore,the pair $NO_2$ and $O_3$ both possess a permanent dipole moment.

Which of the following pairs of molecules will have a permanent dipole moment?
