1. The compound diazene, H2N2, is used in organic synthesis. This compound can exist as two distinct species, one that is polar and one that is nonpolar. Draw the Lewis structures for the polar and nonpolar forms of diazene and label the structures as “polar” or “nonpolar”.
Subsequently, one may also ask, what is polarity of molecules?
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.
Why is phosphine polar?
Phosphine looks like this: It's polar because it has a lone pair of electrons on one side and three hydrogens (positive charge) in a clump on the other side. It is not planar.
Is ch3oh a polar or nonpolar molecule?
If you look at the Lewis structure for CH3OH it does not appear a symmetrical molecule. However, to determine if CH3OH is polar we must consider the molecular geometry. In CH3OH the sharing is not equal and there is a net dipole. Therefore, CH3OH- is a polar molecule.
