Problem

What type(s) of intermolecular forces are expected between  SeOF2 molecules? Choose all that apply.

a. dispersion

b. dipole-dipole

c. ion-ion

d. hydrogen bonding

Solution

We’re being asked to identify the intermolecular forcespresent in SeOF2.


Recall that there are several types of intermolecular forces:

1. Ion-dipole interaction – occurs between an ion and a polar covalent compound

2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F

3. Dipole-dipole interaction – occurs between two polar covalent compounds

4. Induced-dipole interaction – occurs when a nonpolar compound interacts with a polar compound

5. Dispersion forces – occurs in all compounds. This is the primary intermolecular force exhibited by nonpolar compounds.


For this problem, we 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 and IMF of the molecule.
