The Azide Ion, N₃^-, Is Very Reactive Although It Is

question 102

Multiple Choice

The azide ion, N₃^-, is very reactive although it is isoelectronic with the very stable CO₂ molecule. This reactivity is reasonable considering that

• A) a Lewis structure cannot be written for the azide ion that has nitrogen formal charges of zero.
• B) there is no valid Lewis structure possible for the azide ion.
• C) there are resonance structures for azide ion but not for carbon dioxide.
• D) nitrogen cannot form multiple bonds.
• E) charged species always decompose in solution.

Understand the concept of formal charge and its calculation in the context of molecular structures.

Describe the principles of ionic and covalent bonding and identify examples of each.

Utilize the concept of hybridization to describe the bonding in complex molecules.

Predict the geometry of molecules and ions using the VSEPR theory.
