Problem: Which of the following molecules has a net dipole moment (i.e. is polar)?A. KrF2     B. CCl4      C. CO2      D. BeCl2     E. SF2

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.
