In-Lab Model 2: Donating electrons by resonance Substituents with a lone pair on the atom directly attached to the benzene ring can delocalize the charge into the ring which can be called "donating electrons by resonance" Examples: -NH2, -OH -OR Note that these substituents can also withdraw electrons inductively because they are more electronegative than hydrogen. You will have some competing effects, for these substituents the donating resonance effects are stronger than the inductive withdrawing effects. 8. (Choose one answer) Substituents that donate electrons into the rings make the benzene ring MORE/LESS reactive to EAS 9. (Choose one answer) These substituents referred to in question 8 are called ACTIVATING/DEACTIVING substituents. 10. Draw the structure for phenol, including the lone pair electrons on the oxygen atom.

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
