Question

what is the correct name for sno?
tin monoxide
tin (ii) oxide
stannic oxide
tin oxide

Explanation:

Tin (Sn) can have multiple oxidation states. In SnO, oxygen has an oxidation state of - 2. Let the oxidation state of Sn be \(x\). Using the rule that the sum of oxidation states in a neutral compound is zero (\(x+(-2)=0\)), we find \(x = + 2\). For metals with variable oxidation states, we use Roman numerals in the name. So, SnO is named Tin (II) oxide. Tin monoxide is not the correct systematic name as it doesn't indicate the oxidation state. Stannic oxide is \(SnO_{2}\) (where Sn has an oxidation state of + 4). Just "Tin oxide" is too vague without specifying the oxidation state.

Answer:

Tin (II) oxide
