What is the nature of the bonding in C2H2Cl2 , Is it polar?
In order to answer this we must know about dipole moments. Dipole moments need knowledge of geometry and polarity Polarity comes from periodic properties like electronegativity Geometry comes from lewis structures and understanding the nature of electrons.
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
As a general rule, MXn molecules (where M represents a central atom and X represents terminal atoms; n = 2 – 5) are polar if there is one or more lone pairs of electrons on M. NH3 (M = N, X = H, n = 3) is an example. There aretwo molecular structures with lone pairs that are exceptions to this rule. What are they?
