A few mistakes on this answer key:
1. The haworth structure for fructofuranose should have CH2OH instead of H on the first carbon immediately right of the oxygen at the top of the ring.
2. On page 4 number 3a, the extended structural formula should include two lone pairs of electrons on each oxygen.
3. On page 4 number 3c, in the third step of the mechanism the CH3-CH2-O molecule should not directly remove the H from from the carboxyllic acid. You should first add a hydrogen to the CH3-CH2-O to make ethanol. Do this by drawing an arrow from the negatively charged oxygen to a hydrogen on the water molecule. This step will produce ethanol and -OH. Then use the -OH molecule to remove the H from the carboxyllic acid. Do this by drawing an arrow from -OH to the H on the carboxyllic acid.
4. On page 6 number 5b iii, the answer should be 3-methyl-6-nonanol.
(Disclaimer: I didn't make this answer key...)
