The IUPAC name of AlCl3.4(EtOH) is Aluminium(III) chloride-4-ethanol.
Explanation:
- The IUPAC nomenclature system is used to systematically name chemical compounds. It follows a set of rules to assign names to compounds based on their structure and composition.
- In this compound, AlCl3 is the main component, which is aluminium chloride. The presence of 4 molecules of ethanol (C2H5OH) is also indicated.
- Let's break down the IUPAC name step by step:
1. Identify the central atom: The central atom in this compound is aluminium (Al).
2. Determine the oxidation state of the central atom: Aluminium has an oxidation state of +3 in this compound.
3. Name the ligand: The ligand in this compound is chloride (Cl-).
4. Specify the number of ligands: The subscript 3 indicates that there are three chloride ligands.
5. Determine the coordination number: The coordination number is the total number of ligands attached to the central atom. In this case, the coordination number is 3 because there are three chloride ligands.
6. Indicate the presence of ethanol: The presence of 4 molecules of ethanol (EtOH) is indicated by the number 4 outside the parentheses.
7. Name the ethanol ligand: The ligand ethanol is named as ethanol in the IUPAC system.
8. Combine all the information: Putting everything together, the compound is named as Aluminium(III) chloride-4-ethanol. The roman numeral III indicates the oxidation state of aluminium, and the number 4 indicates the presence of four ethanol molecules.
Therefore, the correct IUPAC name for AlCl3.4(EtOH) is Aluminium(III) chloride-4-ethanol (Option A).
