The name of the molecular compound, PCl₅ is d. Phosphorus pentachloride

Further explanation  

The naming of chemical compounds is giving a special name to a compound that aims to facilitate the classification of compounds and facilitate the identification of a compound. The rules for naming chemical compounds have been determined by the IUPAC (International Union of Pure and Applied Chemistry)  

This nomenclature includes the names of ion compounds, covalent compounds, and polyatomics  

For ionic compounds consisting of cations (ions +) and anions (ions -)  

The naming is preceded by the cation then the anion with the -ide suffix added  

Generally for this ion compound consists of metal elements as cations and non-metals as anions  

  • 1. For metal and non-metal compounds  

Metal: cation, positively charged.  

Nonmetal: negative anion.  

The anion cation's charge is crossed  

Example:  

Fe₂S₃  

Fe charge = +3  

S charge = -2  

The name: metal + non-metal + -ide  

Example: BaCl₂ -> Barium chloride  

For transition metals, which have several oxidation charges / numbers, write the oxidation number in roman numbers  

Example:  

SnO: lead (II) oxide  

SnO₂: lead (IV) oxide  

  • 2. For non-metal and non-metal compounds  

The naming: non-metal + non-metal + suffix -ide name  

In the elements given the prefix mono, di, tri, tetra, penta if more than one element is formed  

Example:  

SO₂: Sulfur dioxide  

SO₃: Sulfur trioxide  

PCl₅ is a compound with a bond between nonmetals and nonmetals and is included in a nonpolar covalent bond

PCl₅ is formed from the phosphorus element which binds 5 chlorine elements so that the naming follows the rules:

 non-metal + non-metal + suffix -ide

so the naming becomes

Phosphorus pentachloride
