Vedclass · Answer

(A) molecule has a permanent dipole moment if its net dipole moment $\mu_{net} 
eq 0$.$(i)$ $CH_2Cl_2$ (dichloromethane) has a tetrahedral geometry where the bond dipoles do not cancel out,so $\mu_{net} 
eq 0$.$(ii)$ $trans-1,2-dichloroethene$ is a symmetrical molecule where the bond dipoles cancel each other,so $\mu_{net} = 0$.$(iii)$ $CCl_4$ (carbon tetrachloride) is a highly symmetrical tetrahedral molecule where all four $C-Cl$ bond dipoles cancel out,so $\mu_{net} = 0$.$(iv)$ $Br-C \equiv C-Br$ ($1$,$2$-dibromoethyne) is a linear,symmetrical molecule where the bond dipoles cancel each other,so $\mu_{net} = 0$.Therefore,only compound $(i)$ has a permanent dipole moment.

Which compound among the following will have a permanent dipole moment?
