Question

use naming rules to explain why the following statement is not correct. \the name of the formula pbcl₄ is lead tetrachloride.\

Explanation:

Lead (Pb) is a transition - metal with multiple oxidation states. In $PbCl_4$, lead has an oxidation state of + 4. According to the rules for naming ionic compounds with transition - metals, the oxidation state of the metal should be indicated using Roman numerals in the name. So the correct name should be lead(IV) chloride, not lead tetrachloride which does not follow the proper naming convention for transition - metal compounds.

Answer:

The correct name should be lead(IV) chloride because lead is a transition - metal and its oxidation state (+4 in this case) must be indicated with Roman numerals in the compound's name according to naming rules for ionic compounds with transition - metals.
