If a benzene ring has one methyl group as a substituent, will the next substituent add to the benzene ring in the ortho, meta, or para position? Select one: a. para or meta b. para only c. meta only d. ortho only e. ortho or meta f. Ortho or para
Homework Answers
Benzene having methyl group means the name of the structure
is Toluene (C6H5CH3)
THE - CH3 group is weakly activating group so it activates the benzene ring by releasing the electron to the benzene ring then ortho and para positions are ready to undergoes electrophilic substitution so the incoming electrophile or substitutent attached to either ortho position or para position
answer => f . Ortho or Para

When there is an electron-withdrawing group on a benzene ring (eg. compounds such as nitrobenzenebenzoic acid, acetophenone, etc, resonance structures can be drawn that indicate the positions on the benzene ring that are least nucleophilic (because they have a positive charge on the carbon at that position). Because these positions are much less nucleophilic, the substitution reaction will not occur here; instead, substitution will occur at the other position(s) on the ring. As a result, which position(s) are most nucleophilic...
