Considering 1H-NMR analysis of substituted benzenes (for ortho, para, meta nitrobromobenzene and ortho, para dinitro bromobenzene, or meta para dinitrobromobenzene) : What is the splitting patterns for ring hydrogens for the substituted benzenes? Using ??3-bond and 4-bond J coupling constants, what are: ??Relative chemical shifts of ring hydrogens?
In nitration of acetanilide(synthesis of p-nitroaniline) main product is ortho and para. Explain why ortho and para product is major in resonance and mechanism term.
An NH2 substituent in an aromatic ring is: Select one: a. activating ortho-, meta- and para-directing b. deactivating and ortho- and para-directing c. deactivating and meta-directing d. activating and meta-directing e. activating and ortho- and para-directing
