Average Bond Order

How to Calculate Bond Order From Lewis Structures Examples, Practice Problems, Explained, Shortcut

Average Bond Order Example 1

Which compound do you expect to have the stronger N-N bond, N2H2 or N2H4? Explain.

Mothballs are composed of naphthalene, C10H8, a molecule
that consists of two six-membered rings of carbon
fused along an edge, as shown in this incomplete Lewis
structure:

(c) Not all of the C¬C bond lengths in naphthalene are equivalent.
Based on your resonance structures, how many C¬C
bonds in the molecule do you expect to be shorter than
the others?

DC Chem Unit 5 Average Bond order and Formal Charge

Bond order, Bond Length and Bond Strength

Consider the hypothetical molecule A¬A“A with a bent 
shape. Are the following statements true or false? (a) This 
molecule cannot exist. (b) If this molecule exists, it must 
possess an odd electron.

Formal Charge, Resonance, Bond Order

Bond Order, Bond Lengths, and Bond Strengths

A single bond has a bond order of 1, a double bond has a bond order of 2, and a triple bond has a bond of 3.&nbsp;

Resonance & Bond Order

Larger the Average Bond Order, stronger the bond strength and shorter the length of the bond.

What is the bond order of the phosphate–oxygen bonds within the phosphate ion, PO43–?

Lewis Dot Structures: Neutral Compounds

Lewis Dot Structures or Electron Dot Structures&nbsp;are diagrams that show how elements in a molecule use their valence electrons to form bonds.&nbsp;

Average Bond Order represents the average number of chemical bonds between a pair of bond elements.

Lewis Dot Structures: Ions

Lewis Dot Structures of Ions involves losing or gaining valence electrons to draw the most likely structure.&nbsp;

Octet Rule

The&nbsp;Octet Rule states that main-group elements will generally form enough bonds to obtain 8 electrons in their valence shell.&nbsp;

Lewis Dot Symbols

Lewis Dot Symbols represent the outer shell electrons of an element.&nbsp;

Lewis Dot Structures: Sigma & Pi Bonds

Sigma Bonds directly connect element together, while Pi Bonds provide insulation and protection for those bonds.&nbsp;

Lewis Dot Structures: Exceptions

Lewis Dot Structure Exceptions&nbsp;happen when the central element violates the Octet Rule.

Born Haber Cycle

In the Born-Haber Cycle, ionic solids are created through the ionization and eventual combination of elements.&nbsp;

Coulomb's Law

Coulomb's Law is used to determine the forces experienced by charged particles.&nbsp;

Chemical Bonds

A chemical bond is the connection&nbsp;of different elements through the sharing, transferring or pooling of electrons.&nbsp;

Resonance Structures

Resonance Structures are used to represent the different possible bonding arrangements of a molecule.

Lewis Dot Structures: Acids

Drawing the Lewis Dot Structure of Acids&nbsp;involves first drawing the polyatomic anion and then attaching the H+ ion.&nbsp;

Formal Charge

Formal Charge is the charge given to an element within a molecule when assuming equal sharing of electrons between bonded elements.&nbsp;

Bond Energy

Bond Energy is the amount of energy stored within a chemical bond.

Lattice Energy

Lattice Energy&nbsp;is the estimate for the strength of ionic bonds.&nbsp;

Dipole Moment

Dipole arrows are used anytime a molecule possesses a dipole moment, which happens when a molecule is polar.&nbsp;
