Problem: Predict whether each of the following molecules is polar or nonpolar IF, CS2, SO3, PCl3, SF6, IF5.

FREE Expert Solution

We have to determine whether each of the given molecules is polar or nonpolar.


To determine polarity, we will first draw the Lewis structure of a molecule and then draw dipole moment arrows.

A molecule is nonpolar if the dipoles cancel each other and polar if the dipoles do not cancel each other.

Dipoles only cancel each other when are equal and opposite to each other.


Here are the steps to determine the polarity of each molecule.

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: Draw dipole arrows and determine polarity.
