Explanation:

Step1: Determine electron - domains in SO₂

Sulfur in SO₂ has 6 valence electrons. It forms 2 S - O bonds and has 1 lone - pair. So, the number of electron domains is 3 (2 bonding + 1 non - bonding).

Step2: Find electron - domain geometry of SO₂

According to VSEPR, 3 electron domains result in a trigonal planar electron - domain geometry.

Step3: Determine molecular geometry of SO₂

With 1 lone - pair and 2 bonding pairs, the molecular geometry of SO₂ is bent.

Step4: Determine electron - domains in SF₆

Sulfur in SF₆ has 6 valence electrons and forms 6 S - F bonds. There are no lone - pairs on the central sulfur atom. So, the number of electron domains is 6 (6 bonding).

Step5: Find electron - domain geometry of SF₆

According to VSEPR, 6 electron domains result in an octahedral electron - domain geometry.

Step6: Determine molecular geometry of SF₆

Since there are no lone - pairs and 6 bonding pairs, the molecular geometry of SF₆ is octahedral.
