Question:

True or False: A resonance curved arrow points to where the electrons being

redistributed begin

Answer:

False

Question:

Why was the theory of atomic orbital hybridization developed?

Answer:

It was developed because it explains the difference between electron configuration and the Lewis dot diagram of an element that could be different in valence electrons.

Question:

Draw resonance structure B obtained by redistributing the electrons in the azide ion (N3-).What is the formula charges? What is the overall charge?Are the two resonance forms equivalent contributors to the hybrid structure?

Answer:

A) N(I)= 0, N(II)=0, N(III)= -1

• -1 overall
• No because they have different charges on different atoms and different

bonding patterns
