... Ketones are very similar to aldehydes except the double bond is not at the end of a carbon chain Their names have ‘–one’ as a suffix e.g. propanone, butanone… The smaller ketones are the same as aldehydes. They are liquids because of their polar bonding The smaller molecules (below hexanone) are sol ...

... At equilibrium, the rate of each reaction will be the same. What effect will this have on the amounts of A, B, C and D? Remember both reactions are still happening, but because they are doing so at the same rate the amounts of reactants and products remain constant. (It’s a bit like going up an esca ...
