Question
Groups in these reactions can be classified as ortho, meta, or para directors. For 10 points each:
[10m] Name this general class of substitution reactions in which atoms seeking negative charges attack substituents on rings. The Friedel–Crafts acylation and alkylation are two examples of this type of reaction.
ANSWER: electrophilic aromatic substitution [or EAS]
[10h] Although ortho and para directors, or activators, are usually electron-donating groups, and meta directors are usually deactivating and electron-withdrawing groups, these substituents are notably activating while being EWGs.
ANSWER: halogens [accept specific halogens like fluorine or chlorine or bromine or iodine]
[10e] The effects of various directors in EAS reactions are typically determined by substituting this compound and observing its reactions. This simple aromatic compound’s chemical formula is C6H6.
ANSWER: benzene
