Question
1.Which of the following would react faster than benzene in an electrophilic aromatic substitution reaction?
acetophenone
benzoic acid
anisole
chlorobenzene
2.Which of the following would react slower than benzene in an electrophilic aromatic substitution reaction?
benzaldehyde
phenol
toluene
aniline
3.If an electrophile was added to acetophenone via an electrophilic aromatic substitution, at what position(s) of the ring would the electrophile add?
ortho
meta
ortho
para only
4.If an electrophile was added to toluene via an electrophilic aromatic substitution, at what position(s) of the ring would the electrophile add?
ortho
para only
ortho
meta
5.If an electrophile was added to nitrobenzene via an electrophilic aromatic substitution, at what position(s) of the ring would the electrophile add?
meta
ortho
para only
mix of ortho and para
acetophenone
b.benzoic acid
c.anisole
d.chlorobenzene
Explanation / Answer
1) option C is correct (-OCH3 group on benzene ring is an electron donating group which activates the benzene ring and allows electorphile to attack on benzene ring.)
2) Option A is correct (-CHO group on benzene ring an electron withdrawing group which withdraws electrons and deactivates benzene ring.)
3) option B is correct ( acetyl group on benzene ring is an electron withdrawing group so it directs the new incoming electorphile to attack on meta position.)
4) option B is correct
5) option A is correct (nitro group is an electron withdrawing group so it directs new electrophile to meta position.)
