Interpretation: The formal charge on
Concept introduction: Lewis structure is a representation of molecules in which dots are shown to represent unshared electrons and lines are shown to represent bonds. These lines and dots represent distribution of electrons in the molecule.
When one single structure is unable to describe all the properties of a single-molecule, a phenomenon called resonance comes into play. This arises when two or more than two Lewis structures are possible for one molecule. All such structures are called resonating structures and have same placement of atoms in them but these have different locations of bond pairs and lone pairs. The resonating structures are inter-convertible with each other. The resultant of all the resonating or contributing structures is called the resonance hybrid.

Organic Chemistry: A Guided Inquiry
- Cyclopropane is an interesting hydrocarbon. Instead of havingthree carbons in a row, the three carbons form a ring, asshown in this perspective drawing (see Figure 2.18 for a priorexample of this kind of drawing): Cyclopropane was at one time used as an anesthetic, but its use was discontinued, in part because it is highly flammable.(a) What is the empirical formula of cyclopropane? Howdoes it differ from that of propane? (b) The three carbon atomsare necessarily in a plane. What do the different wedgesmean? (c) What change would you make to the structureshown to illustrate chlorocyclopropane? Are there isomers ofchlorocyclopropane?arrow_forwardQ3.
