Part 9 : STRUCTURE DETERMINATION

Note that these types of questions are often the most difficult on the examination. This is because they are holistic in that they require a good understanding of the reactions and the concepts and the ability to apply those concepts. They can't be memorised, they require understanding and ability to apply. Hence they help discriminate those who truly understand from those who have memorised and will soon forget.

A full schematic of the full solution is presented below.

The key structure (where we know the most) is the named structure that undergoes a radical substitution to give B. From B we can deduce C & D, then E and F. From B we can work out A then G then H.
