Ncl3 Polar Or Nonpolar
Is ncl3 polar or non-polar?
So, since the electronegativity for nitrogen and chlorine is 3.0, the difference is 0 (your book is correct)
Next, we see which category 0 is according to the electronegativity difference scale:
0.0 0.3 = non-polar harmony.
0.3 1.7 = harmonious polar.
1.7 3.3 = Ionic.
This means that NCl3 is a non-polar compatible molecule.
But nitrogen has 3 bonds and only 1 pair of electrons, that's a total of 5 pairs of electrons. (Since each bond contributes 1 electron to nitrogen and a PAR contains 2 electrons, making a total of 5 electrons nitrogen). This means that the molecule is a triangular pyramidal. This means that there is a difference of 90 degrees and 120 degrees that separates each link.
If all three have the same electronegativity, then NCl3 is non-polar. It has isolated pairs, which means it has a tetrahedral shape instead of the manual triangular planner shape. Generally, molecules in the shape of a triangular plane are polar because the electronegativity is higher in the central atom. Go
