Questions & Step-by-Step Solutions

Which of the following compounds contains a p-block element in its highest oxidation state? (2023)
  • Step 1: Identify the compounds given in the question.
  • Step 2: Understand what a p-block element is. P-block elements are found in groups 13 to 18 of the periodic table.
  • Step 3: Look for the highest oxidation state of the p-block elements in the compounds.
  • Step 4: In PCl5, phosphorus (P) is a p-block element.
  • Step 5: Determine the oxidation state of phosphorus in PCl5. It is +5 because it forms five bonds with chlorine (Cl).
  • Step 6: Conclude that PCl5 contains a p-block element (phosphorus) in its highest oxidation state of +5.
