Problem 92P

Classify each molecule as polar or nonpolar.

(a) $$\mathrm{N}_{2} \mathrm{H}_{2}$$

(b) $$\mathrm{H}_{2} \mathrm{O}_{2}$$

(c) $$\mathrm{CF}_{4}$$

(d) $$\mathrm{NO}_{2}$$

Step-by-Step Solution:

Step 1 of 4

a)

Polar compounds:

The electronegative difference between the species in the range of 0.3 to 1.4 is considered polar compounds.

Example: $$\mathrm{HCl}$$ and $$\mathrm{HF}$$

Nonpolar compounds:

The electronegative differences between the species in the range of 0 to 0.2 are considered as non-polar compounds.

The given molecule $$\mathrm{N}_{2} \mathrm{H}_{2}$$.

The electronegativity of nitrogen - 3.0

The electronegativity of hydrogen - 2.1

Total difference - 0.9

The shape of molecules with bond dipoles $$\mathrm{N}_{2} \mathrm{H}_{2}$$ is as follows.

Shape of the molecule is nonlinear.

In the transform of the molecule, the net dipole moment is zero therefore, the given molecule is non - polar in the transform.

The net dipole moment is non - zero in cis form.

Therefore, the given molecule is polar in the cis form.
