  1. Question 1

    Q1. In a Wurtz synthesis, 0.4 moles of methyl iodide react with sodium in ether. How many moles of ethane are produced?

    • A) 0.4 moles
    • B) 0.8 moles
    • C) 0.2 moles
    • D) 0.1 moles

    Answer: 0.2 moles

    Explanation: Wurtz reaction uses 2 moles of RX to produce 1 mole of alkane; 0.4 moles RX yields 0.2 moles ethane. Option B ignores stoichiometry.
