Question 1: Compare the possible ring
structures and conformers for fructose and decide which is
preferred (if any). There are four main hemi-ketal rings, one of
which is shown below. What factors might influence the preference
for 5- or 6-membered rings?
Question 2: Make a model of vitamin C. Note the
lactone link that forms the ring, rather than the hemi-ketal that
is present in fructose. Do you think the presence of sp2
carbons in the ring induce strain? Does...
