Identify the intermolecular forces in each of the following compounds: NOCl, NH2Cl, SiCl4
I'm not interested in the answers so much as *how* you got the answers. Help please?
you know about hydrogne bonds, diipole forces and induced dipole forces
Hydrogen bonds are easy to me, it's the dipole-dipole and induced dipole forces i have a hard time with. I don't know how to identify whether the elements involved are polar or nonpolar...
can i determine this just by looking at the periodic table? I'm not sure but i think it has something to do with electronegativities, and i'm familiar with the electronegativity trends on the periodic table.
Dipole-Dipole force is the force in between between two different polar molecules( has a dipole moment). (Dipole moment a separation of charge around a molecules into a more positive area and negative area.) Induced dipole if we have methane and water, methane is non polar because in order for a molecule to be polar you got to have geometrical asymmetry. CH4(methane) is tetrahedral arranged ,these molecules have polar bonds but the molecules themselves are not polar because the symmetry of the bonds cancels the asymmetry of charge. |dw:1406119092771:dw| |dw:1406119556969:dw|
C-H bonds are not polarized, their \(\Delta E_n\) is not large enough for there to be difference is electron distribution so as to categorize them as so. The reasoning you provided was sound, but you should've used another molecule for your example, like \(CCl_4\).
