ANSWER:

Solution 86P  

Here, we are going to classify the molecules as polar or nonpolar. Polarity of a molecule can be determined as follows.

  1. Determining the geometry of the molecule.
  2. A molecule is said to be polar when the two bonding atoms have sufficiently different electronegativities.
  3. Determination of the dipole moment of the molecule.

(a) I2 

Step 1: The Lewis structure of the molecule is as follows

The molecule contains one bonding electron pair and 6 lone pair of electrons. Therefore, I2 is a linear molecule.
