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
