Question
(This is a multiple choice question). Answer choices are:
A) Fluorine is the worst at withdrawing electrons inductively. But fluorine is the best at donating electrons by resonance because its 2p orbital compared with the 3p orbital of chlorine, the 4p orbital of bromine, or the 5p orbital of iodine can better overlap the 2p orbital of carbon when it forms a ? bond. The two factors result in fluorine being the weakest deactivator of the halogens.
B) Fluorine is the best at withdrawing electrons inductively. Fluorine is also best at donating electrons by resonance because its 2p orbital compared with the 3p orbital of chlorine, the 4p orbital of bromine, or the 5p orbital of iodine can better overlap the 2p orbital of carbon when it forms a ? bond. Since fluorine is the weakest deactivator of the halogens, electron donation by resonance must be the more important factor in determining the relative reactivities of halo-substituted benzenes.
C) Fluorine is the best at withdrawing electrons inductively. But fluorine is the worst at donating electrons by resonance because its 2p orbital compared with the 3p orbital of chlorine, the 4p orbital of bromine, or the 5p orbital of iodine cannot overlap the 2p orbital of carbon when it forms a ? bond. The two factors result in fluorine being the strongest deactivator of the halogens.
D) Fluorine is the worst at withdrawing electrons inductively. Fluorine is also worst at donating electrons by resonance because its 2p orbital compared with the 3p orbital of chlorine, the 4p orbital of bromine, or the 5p orbital of iodine cannot overlap the 2p orbital of carbon when it forms a ? bond.

Explain why the halo-substituted benzenes have the relative reactivities shown in the table below Table 19.1 The Effects of Substituents on the Reactivity of a Benzene Ring Toward Electrophlic Aromatic Substitution Activating substituents Most activating -NHR -NR2 Strongly activating 0 Moderately activating -NH CR Ortho/para directing Weakly activating -CH-CHR Standard of comparison -H Deactivating substituents -F Weakly deactivating Moderately deactivating OR Meta directing SO,H Strongly deactivatingExplanation / Answer
answer:
B) Fluorine is the best at withdrawing electrons inductively. Fluorine is also best at donating electrons by resonance because its 2p orbital compared with the 3p orbital of chlorine, the 4p orbital of bromine, or the 5p orbital of iodine can better overlap the 2p orbital of carbon when it forms a bond. Since fluorine is the weakest deactivator of the halogens, electron donation by resonance must be the more important factor in determining the relative reactivities of halo-substituted benzenes.
