Question

2. Draw the Lewis structure for sulfur dioxide. [1pt] xide, izotts Size a. What is the molecular geometry of this molecule? (0.5pt] b. Is this molecule polar or non-polar? [0.5pt] c. Identify all the intermolecular forces that would act between two molecules of sulfur dioxide. [1pt]

Answer 1

Steps to draw Lewis structure :- 1. Write the chemical symbols of each element involved in the structure. 2. Count the number of lone pairs and bond pairs of electrons on each atom. 3. Single bonds are represented by single line , double bond by double line and triple bond by triple line between the bonded atoms.

The forces which mediate the interaction between the molecules are known as intermolecular forces. Intermolecular forces are of 3 types:- 1. Hydrogen bonding -- When hydrogen is bonded to a highly elecrtonegative atom like Flourine , oxygen or nitrogen then it forms a weak bond known as hydrogen bond. Dipole dipole forces -- In polar molecules negative end of one molecule attracts the positive end of the other molecule. It is called Dipole forces. It is present only in polar molecules. Dispersion forces -- It arises when electrons in an atom occupies positions that results in temporary Dipoles. It is present in nonpolar molecule.
intermolecular forces in SO2 are London dispersion forces and dipole-dipole forces.
