MDCAT Chemistry MCQ #5372

  1. Question 1

    Q1. Comparing the allotropes of Phosphorus, White phosphorus is much more reactive and poisonous than Red phosphorus because White phosphorus:

    • A) White phosphorus is a polymer and less reactive
    • B) Red phosphorus consists of discrete P4 molecules
    • C) White phosphorus consists of discrete P4 tetrahedral molecules
    • D) Red phosphorus is soluble in Carbon disulfide

    Answer: White phosphorus consists of discrete P4 tetrahedral molecules

    Explanation: White phosphorus consists of discrete P4 molecules and is highly reactive, whereas Red phosphorus is a stable macromolecular polymer.
