Spell out the full name of the compound. CuNO
The correct answer and explanation is :
The correct name of the compound CuNO is Copper(I) Nitrite.
Explanation:
- Understanding the Components of CuNO
- Cu (Copper): Copper is a transition metal that can exhibit multiple oxidation states, commonly +1 (Copper(I)) and +2 (Copper(II)).
- NO (Nitrite Ion): The nitrite ion is a polyatomic ion with the formula NO₂⁻, but in this case, there is only NO, which is not a standard ion.
- Oxidation State Determination
- Copper in CuNO must balance the charge of the nitrite ion.
- Since nitrite usually has a charge of -1 (NO₂⁻), and copper can take different oxidation states, we assume CuNO is Copper(I) Nitrite, meaning copper has a +1 charge.
- If Cu were Copper(II) (+2 charge), we would expect Cu(NO₂)₂ instead of CuNO.
- Naming Convention
- The metal (Cu) is named first, followed by its oxidation state in Roman numerals in parentheses.
- The non-metal part (NO, from the nitrite ion) follows, keeping its ion name as “nitrite.”
Final Answer: Copper(I) Nitrite
This name follows the standard IUPAC nomenclature for transition metals and polyatomic ions.
