0=c=0;
Lewis electron-dot diagrams for CO2 and SO2 are given above. The molecular geometry and polarity of the two substances are
the same because the molecular formulas are similar
the same because C and S have similar electronegativity values
different because the lone pair of electrons on the S atom make it the negative end of a dipole
D
different because S has a greater number of electron domains (regions of electron density) surrounding it than C has
