Type of reaction

  1. Feb 7, 2016 #1
    Hi everyone. I'm a high school student. Recently I have been doing some past papers to prepare for the public exam in April. The reaction "ethene + steam ----> ethanol" is given and I was asked to name the type of reaction. I answered oxidation but the answer is addition. Later I asked my teacher and he said oxidation is wrong as the change in oxidation number is hard to find. What I think is simply that there's an extra O atom added to the compound. Is this thought wrong?

    ... and, water has been reduced .... It's an "addition."

    How can we find the change in oxidation number in the reaction? Is it possible?

    In general? Count electrons.
    Not for an addition reaction; the single product is the combination of two reactants, one of which may have been oxidized and the other reduced. But, which is which?
