Question

what is the correct name for the compound with the formula sncl4?
tin (vi) chloride
tin (ii) chloride
tin tetrachloride
tin (iv) chloride

Explanation:

• For ionic compounds with metals that have variable oxidation states (like tin, \(Sn\)), we first determine the oxidation state of the metal.
• Chloride ion (\(Cl^-\)) has an oxidation state of \(- 1\). In \(SnCl_4\), let the oxidation state of \(Sn\) be \(x\). Using the rule that the sum of oxidation states in a neutral compound is zero: \(x+4\times(-1)=0\), so \(x = + 4\).
• The naming convention for such compounds is: metal name (oxidation state in Roman numerals) + non - metal base name + “ide”.

Answer:

Tin (IV) chloride
