Which substance below is resonance stabilized by delocalized pi electrons?
a. Benzene
b. Hydrochloric acid
c. Hydrogen gas
d. Methane
e. Potassium bromide
Answer (2)
If you do not this, I suggest brushing up on delocalization as well as sigma/pi bonds. Benzene is the only one of the 5 with any pi bonds, so this should be a relatively easy question if you are familiar with the concepts. I would search up a detailed (not to detailed though) explanation of both.
Benzene is the only substance listed that is resonance stabilized by delocalized pi electrons. It can be represented by multiple resonance structures, leading to its stability. The other options do not exhibit resonance as they lack delocalized electrons.
