Chapter 4: Problem 23

What is the role of Roman numerals in the names of the compounds formed by transition metals?

Short Answer

Expert verified
Answer: Roman numerals are used in naming compounds formed by transition metals to indicate the specific oxidation state of the metal in that particular compound. This helps differentiate between different compounds formed by the same transition metal with different oxidation states. The inclusion of Roman numerals in the name follows the IUPAC naming conventions, providing a clear identification of the oxidation state and avoiding any ambiguity.

Step by step solution

01

1. Understanding Transition Metals

Transition metals are elements found in the d-block of the periodic table, having partially filled (n-1) d-subshells. These elements often exhibit variable oxidation states, unlike their counterparts in the main groups, due to which they form numerous different compounds with varying charges.

2. Understanding Oxidation States

An oxidation state refers to the degree of oxidation that an atom has within a molecule or an ion. Transition metals have multiple oxidation states due to the availability of multiple valence electrons that can be shared or lost in chemical bonds. For instance, iron (Fe) can have oxidation states of +2 or +3, depending on the bonding scenario.

3. IUPAC Naming for Compounds Formed by Transition Metals

The International Union of Pure and Applied Chemistry (IUPAC) has developed a systematic method for naming compounds. In the IUPAC system, the oxidation state of a transition metal in a compound is typically indicated by a Roman numeral inside brackets and placed after the metal's name. This allows for clear identification of the oxidation state, thus avoiding any ambiguity that may arise due to multiple oxidation states.

4. Role of Roman Numerals in Naming Compounds of Transition Metals

Roman numerals are included in the names of the compounds formed by transition metals to indicate the specific oxidation state of the metal in that particular compound. This helps differentiate between different compounds formed by the same transition metal with different oxidation states. For example, if we are referring to a compound containing the +2 or +3 oxidation states of iron, we would name it as Iron(II) or Iron(III), respectively.
