Solution Summary: The author compares the concept of resonance to that of rhinoceros, which is a hybrid animal of horse and donkey.
The two different analogies for the concept of resonance have to be compared and the more appropriate analogy has to be identified.
Concept Introduction:
Resonance
Resonance is the phenomenon of delocalization of electrons of pi bond (either pi bonding or non-bonding or both) in a molecule such the molecule cannot be represented by a single Lewis structure as the delocalization of electrons gives rise to more than one structure to a same molecule.
Resonance structures
The various structures for a molecule that are formed by delocalization of electrons are termed as resonance structures.
Rules for writing resonance structures
All the resonance structures must have valid and appropriate Lewis structures.
The resonance structure are written and drawn such a way that position of atomic nuclei must not be changed.
Hybridization of atoms in the molecule must not be changed.
The position of bond (electrons) also known as distribution of electrons only must be changed.
All of the atoms involved in resonance and also the atoms that are directly bonded to those atoms must be coplanar (lie in same plane) nearly.
If you include structures in which sulfur has an expanded octet and exclude structures with triple bonds, how many resonance structures can be drawn for sulfur trioxide, SO3?
Complete the following statements about the molecule NBr3. Please note that ALL atoms in this molecule obey the octet rule.
The molecule NBr3 has BLANK total valence electrons.
The molecule NBr3 should be drawn with N in the middle, and the Br atoms on three sides of the N atom.
After drawing the Lewis structure for NBr3 using the above information, it is evident that the three-dimensional shape (or geometry) of the molecule is BLANK , with a bond angle of BLANK degrees.
Decide whether these proposed Lewis structures are reasonable.

Is the proposed Lewis structure reasonable?
O Yes.
O No, it has the wrong number of valence electrons.

The symbols of the problem atoms are:
* If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many
times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "0,0".
