Resonance Chemistry: Basic Inorganic Nomenclature

---

1. What is Resonance in Chemistry?

Resonance is a concept used to describe the delocalization of electrons in molecules where a single Lewis structure is not enough to represent the bonding.

Definition:

Resonance occurs when two or more valid Lewis structures can be drawn for the same molecule, and the actual structure is a hybrid of these forms.

Example:

Ozone (O₃)

It has two resonance structures:

But the actual structure is a resonance hybrid, where both O–O bonds are of equal length.

2. What is Inorganic Nomenclature?

Inorganic nomenclature is the system of naming inorganic compounds based on rules set by IUPAC (International Union of Pure and Applied Chemistry).

3. Basic Inorganic Nomenclature Rules

Binary Ionic Compounds (Metal + Non-metal):

• Name the metal first, then the non-metal with an -ide ending.

Examples:

• NaCl → Sodium chloride

• MgO → Magnesium oxide

---

Transition Metals (with variable charges):

• Use Roman numerals to indicate the metal's oxidation state.

Examples:

• FeCl₂ → Iron(II) chloride

• FeCl₃ → Iron(III) chloride

---

Polyatomic Ions:

Some ions have specific names you must memorize.

Example:

• NaNO₃ → Sodium nitrate

---

Hydrates:

Compounds with water molecules attached.

Example:

• CuSO₄·5H₂O → Copper(II) sulfate pentahydrate

---

Acids:

• Hydro + base name + ic acid (for anions ending in -ide)

  → HCl → Hydrochloric acid

• -ate → -ic acid, -ite → -ous acid

  → HNO₃ (nitrate) → Nitric acid
  → HNO₂ (nitrite) → Nitrous acid

---

Connection Between Resonance & Nomenclature:

• Resonance affects molecular structure and stability, but not the name of the compound.

• However, understanding electron delocalization is essential for drawing correct structures and predicting compound behavior.
