|
Draw and name the organic product of the reaction between phenol and bromine.
|
In an unsubstituted benzene ring, why are all six carbon atoms chemically equivalent?
due to the delocalised pi electron system
due to the double bonds between them
due to the single bonds between them
due to the lack of any functional groups
|
What effect does introducing a functional group have on the electron density of a benzene ring?
it makes all carbons less reactive towards electrophiles
it does not affect the electron density
it alters the electron density at specific carbons
it makes all carbons more reactive towards electrophiles
|
Which positions on a benzene ring do electron-donating groups activate for electrophilic attack?
carbons 3- and 5-
carbons 2- and 4-
carbons 2-, 4-, and 6-
carbons 1-, 3-, and 5-
|
How do electron-donating groups activate specific positions on a benzene ring for electrophilic attack?
by pulling electron density away from those positions
by decreasing the electron density at those positions
by having no effect on the electron density at those positions
by increasing the electron density at those positions
|
Which positions on a benzene ring do electron-withdrawing groups activate for electrophilic attack?
carbons 3- and 5-
carbons 2- and 4-
carbons 2-, 4-, and 6-
carbons 1-, 3-, and 5-
|
How do electron-withdrawing groups activate specific positions on a benzene ring for electrophilic attack?
by having no effect on the electron density at those positions
by increasing the electron density at those positions
by retaining relatively more electron density at those positions
by contributing electrons to those positions
|
Is the nitro (-NO2) group an example of an electron-donating or electron-withdrawing group?
electron-donating
electron-withdrawing
