Polarity and Structure of HNO3

The video tutorial explores the polarity of HNO3 by examining its Lewis structure and molecular surface. It highlights the asymmetrical nature of the molecule, with hydrogen and oxygen atoms creating distinct poles. The electrostatic potential analysis confirms that HNO3 is a polar molecule, as it has both positive and negative sides. Dr. B concludes the tutorial by affirming the polar nature of HNO3.

What is the initial step to determine if HNO3 is polar?

• Check its boiling point

• Analyze its color

• Examine its Lewis structure

• Measure its density

Why is HNO3 considered asymmetrical?

• Because it has equal distribution of atoms

• Because it forms a perfect triangle

• Due to the presence of a central carbon atom

• Because hydrogen and oxygen are on different sides

In the visual representation of HNO3, what color is used to represent nitrogen?

• Green

• White

• Blue

• Red

What does the electrostatic potential surface of HNO3 indicate?

• The molecule has no charge

• The molecule is non-polar

• The molecule is symmetrical

• The molecule has both positive and negative sides

Which part of HNO3 has a more positive electrostatic potential?

• Nitrogen

• Oxygen

• Hydrogen

• The entire molecule

What conclusion is drawn about the polarity of HNO3?

• It is a polar molecule

• It is a non-polar molecule

• It is a metallic compound

• It is an ionic compound
