Molecular Geometry of NO2

The video tutorial explains the molecular geometry of NO2 using the Lewis structure and VSEPR theory. It describes how the presence of two oxygen atoms and a single electron on the nitrogen atom leads to a bent molecular shape rather than a linear one. The tutorial also introduces the AXE notation to confirm the geometry and discusses the bond angle, which is approximately 120 degrees. The video concludes with a summary of the molecular geometry of NO2.

What is the first step in determining the molecular geometry of NO2?

• Counting valence electrons

• Measuring bond angles

• Drawing the Lewis structure

• Using the periodic table

Which theory is used to explain the molecular geometry of NO2?

• Bohr's theory

• Quantum theory

• VSEPR theory

• Molecular orbital theory

Why is NO2 not a linear molecule?

• Because of the presence of a lone electron

• Due to its high electronegativity

• Because it has three oxygen atoms

• Due to its ionic nature

What is the significance of the lone electron in NO2's geometry?

• It attracts the oxygen atoms

• It repels the oxygen atoms, causing a bent shape

• It forms a bond with nitrogen

• It has no effect on the geometry

What does the 'X' represent in the AXE notation for NO2?

• The number of atoms attached to the central atom

• The number of lone pairs

• The bond angle

• The central atom

What is the AXE notation for NO2?

• AX2E1

• AX1E1

• AX3E0

• AX2E2

How can the molecular geometry of NO2 be confirmed using a table?

• By analyzing the electron configuration

• By measuring the molecular weight

• By comparing with AXE notations

• By checking the bond length

What is the approximate bond angle in NO2?

• 120°

• 180°

• 90°

• 109.5°

What is the role of the central nitrogen atom in NO2's geometry?

• It forms a tetrahedral structure

• It forms a linear structure

• It acts as a central point for the bent shape

• It does not participate in bonding
