Resonance Structures

________________ are two Lewis structures with the same placement of atoms, but a different arrangement of electrons

_______________ is a composite of all possible resonance structures, representing the electron pairs with different locations of individual resonance structures as delocalized

molecules that can have two or more different Lewis structures

• Lewis structures

• central atom

• terminal atom

• resonance structures

Resonance structures are two or more Lewis structures that differ only in the placement of

• atoms

• electrons

• bonds

• nuclei

The concept of resonance is used to describe molecules that cannot be represented by a single

• Lewis structure

• Molecular formula

• Empirical formula

• Structural formula

Which of the following is true about resonance structures?

• They have different arrangements of atoms

• They have different arrangements of electrons

• They have different molecular formulas

• They have different numbers of atoms

In resonance structures, the actual structure of the molecule is a

• resonance hybrid

• single structure

• mixture of structures

• none of the above

Resonance structures are used to represent molecules with

• localized electrons

• delocalized electrons

• fixed electrons

• no electrons

Which of the following molecules can exhibit resonance?

The resonance hybrid is more stable than any individual resonance structure because

• it has lower energy

• it has higher energy

• it has more atoms

• it has fewer atoms
