  1. Question 1

    Q1. During the Clemmensen reduction of 1 mole of propanone to propane, what is the net decrease in the molar mass of the organic compound?

    • A) 16 g
    • B) 14 g
    • C) 18 g
    • D) 2 g

    Answer: 14 g

    Explanation: Clemmensen reduction replaces =O (16) with two -H (2), a net loss of 14g/mol. 16g is tempting but ignores the added hydrogens.
