4 cards from this section. Quick, good the night before a test.
Define bond energy.
Think of it as the energy needed to separate atoms held together by that bond.
What is a resonance structure?
Consider structures that show various electron arrangements.
What is bond energy?
Think about energy changes during bond formation and breakage.
True or False: Resonance structures represent the only configuration of electron distribution in a molecule.
How many ways can a molecule's electrons be represented?
Given the bond energy values for C–C single, C=C double, and C≡C triple bonds, discuss the molecular implications of these values for a hexagonal hydrocarbon.
Consider how resonance changes the typical reactivity of carbon bonds.
Draw and explain the resonance structures of the sulfate ion (SO₄²−), determining the bond orders for each S-O bond.
Think about how shifting the double bonds can affect overall stability.
