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.
A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there
are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from
the arrow.
• Is the student's transformation possible? If not, check the box under the drawing area.
. If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts,
inorganic reagents, or other important reaction conditions above and below the arrow.
• You do not need to balance the reaction, but be sure every important organic reactant or product is shown.
