Answer the following about Baldwin’s rules, for 10 points each.
[10e] Baldwin’s rules govern the relative stabilities of organic reactions that form these structures. Five-membered examples of these structures are formed faster than six-membered examples, such as benzene.
ANSWER: rings [accept cyclic or cycles]
[10h] Baldwin’s rules state that these two types of ring closing reactions are favorable for all ring sizes from 3 to 7. Name either. Your answer should be a sequence of two prefixes used in the nomenclature of Baldwin’s rules.
ANSWER: exo-tet OR exo-trig [reject partial answers]
[10m] A counterexample to Baldwin’s rules is the 5-endo-trig formation of a cyclic one of these functional groups. A carbon atom is bonded to the oxygens of two ethers in these groups, unlike related “hemi” groups with one -OR (“O-R”) and one -OH (“O-H”).
ANSWER: acetals [accept ketals; reject “hemiacetals” or “hemiketals”]
