i saw that the above topics have been discarded from the AAMC topic list as of april 2003 -- is this for real? no anti-aromatic vs aromatic? no worries about branching alkynes? can someone confirm or deny this?
It is true that no outside knowledge of alkenes and aromatic compounds is necessary for the MCAT. However, these concept areas are still fair game on the MCAT; it just means that information regarding these classes of compounds must be given in the passage.
I would still study alkenes and aromatic compounds, simply because the MCAT passages are not exactly "reader-friendly". They should be a low priority subject in your preparation, though--certainly not as important as nucleophilic substitution reactions.
