Polarity and Structure of SOCl2

The video tutorial explains the polarity of the SOCl2 molecule by examining its Lewis structure and 3D model. The central sulfur atom is bonded to two chlorine atoms and one oxygen atom, with a lone pair of electrons. Due to the differing electronegativities of these atoms, the molecule is polar. The video highlights the unsymmetrical nature of the molecule, contributing to its polarity. Dr. B concludes by summarizing the key points about the SOCl2 molecule's polarity.

Which of the following atoms is more electronegative in the SOCl2 molecule?

• Oxygen

• Hydrogen

• Chlorine

• Sulfur

In the three-dimensional structure of SOCl2, what color represents sulfur?

• Blue

• Yellow

• Red

• Green

Why is the SOCl2 molecule considered polar?

• It has equal electronegativity among all atoms.

• It has an unbalanced and unsymmetrical structure.

• It has a balanced distribution of charge.

• It has a symmetrical shape.

What is the role of the lone pair of electrons in the polarity of SOCl2?

• It makes the molecule non-polar.

• It balances the molecule.

• It contributes to the asymmetry of the molecule.

• It has no effect on polarity.
