Problem: Would the following structures be polar or nonpolar? (Not applicable if the structure is an ion. Pick "ionic" in that case).NO2+SCN-CS2

FREE Expert Solution

We’re being asked to determine the polar molecule among the choices.


Recall that when a central atom is surrounded by the same element and doesn’t have any lone pairs, the molecule is nonpolar.


To do so, we first need to do the following steps:

Step 1: Determine the central atom in the molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the polarity of the molecule.
