(a)
Interpretation:
The iodo (–I) and formyl (–CHO) groups are not listed in Table 23-1. The relative amounts of ortho and meta nitration products obtained for each substituent are shown here:
The missing information pertaining to the relative amounts of the para isomers that are produced as well as the sum of the amounts of ortho and para products are to be supplied.
Concept introduction:
The substituent on the benzene ring prior to substitution dictates the regiochemistry of the reaction. Some substituents are designated as ortho/para directors because they lead to product mixtures consisting primarily of the ortho- and para-disubstituted products. Other substituents are designated as meta directors because they favor the formation of the meta-disubstituted product. The results from nitration reactions are summarized in Table 23-1:
(b)
Interpretation:
The iodo (
Based on the information, whether each substituent is an ortho/para director or a meta director is to be determined.
