    State, with a reason, the empirical formula of poly(propene).

    Any help much appreciated. The mark scheme says:

    CH2 -the repeat unit since polymer made by addition reaction. I do not understand what this means.

    Thank you in advance for all your help.

    The monomer in polypropene is C3H6.

    In its simplest forms this is CH2.
