The correct Answer is:
To determine the allotrope of phosphorus that is polymeric and consists of chains of P4 tetrahedra linked together, we can analyze the different allotropes of phosphorus: white phosphorus, yellow phosphorus, and red phosphorus. ### Step-by-Step Solution: 1. **Understanding Allotropes of Phosphorus**: - Phosphorus has several allotropes, primarily white, yellow, and red phosphorus. Each allotrope has a distinct structure and properties. 2. **Analyzing White and Yellow Phosphorus**: - Both white and yellow phosphorus consist of P4 tetrahedral units. However, they do not form long chains or polymeric structures. Instead, they exist as discrete P4 molecules. - Therefore, neither white nor yellow phosphorus can be classified as polymeric. 3. **Examining Red Phosphorus**: - Red phosphorus has a different structure. It consists of a network of P atoms that are linked together, forming a polymeric structure. - In red phosphorus, the P4 tetrahedra are connected in chains, creating a larger polymeric network. 4. **Conclusion**: - The allotrope of phosphorus that is polymeric and consists of chains of P4 tetrahedra linked together is **red phosphorus**. ### Final Answer: The allotrope of phosphorus which is polymeric consisting of chains of P4 tetrahedral linked together is **red phosphorus**. ---
