How is delocalization affected by resonance?

Iris Shim 1E

I don't understand why there are two names for acids and bases. Are there instances where a Bronsted acid is not a Lewis acid or a Bronsted base is not a Lewis base or vice versa? What is the difference between the two definitions?

Iris Shim 1E

What does it mean for an acid or base to disassociate completely? How does that affect the reaction and its equilibrium?

Iris Shim 1E

The answer for the Lewis structure for this question says that there are more resonance structures available, but what would be the best resonance structure? And do different resonance structures affect the structure of the molecule?

Iris Shim 1E

Do double or triple bonds affect the structure of a molecule? For example, on question 4.11 part b, there's a double bond between the O and the P, but would it push the other atoms further away affecting the angles in between the atoms, thus the structure?

Iris Shim 1E

If there are lone pairs on an atom that's NOT the central atom, does it affect the angles of the bonding in the VSEPR model?

Iris Shim 1E

For question 4.1 part b, how come the second model may have lone pairs on the central atom? If there was a lone pairs on the central atom, wouldn't the bonding pairs move away from the lone pair making the angle less than 180 degrees?

Even though it is rare, what does it mean when K=1? Qualitatively, how would this affect the reaction in the hypothetical scenario that k=1

When you're drawing the Lewis structure, you have to get minimize the formal charge overall and on each ion. The less formal charge, the more stable it is. The correct answer shown in the book minimizes the overall formal charge.

Iris Shim 1E

When the Lewis structures of molecules have multiple Resonance Structures, what does that mean for the molecule? Does that mean a more stable (has less formal charge) resonance structure occurs more frequently for the molecule in nature than a resonance structure with more formal charge?

Iris Shim 1E

Can someone explain in a concise manner what dipole moments actually do to a molecule? Do they help the molecule bond to other molecules?

Iris Shim 1E

But how is this molecule able to exist in the first place?

Iris Shim 1E

How come in the Lewis structure of ClO, why does chlorine only have 7 electrons? How come the octet rule does not have to be fulfilled with ClO?

Iris Shim 1E

I don't understand how to be able to interpret how to set up the structure for glycine, more specifically the COOH. How do you determine which atom the oxygen atoms for the COOH attach to and where the Hydrogen attaches?

Iris Shim 1E

Do atomic orbitals always form molecular orbitals when they overlap in bonding?

Iris Shim 1E

Why do strong conjugate bases mean a weak acid?

Iris Shim 1E

Does the energy of a photon have to be greater than the work function in order to remove the electron? If the energy of the photon is exactly equal to the work function, would the electron still jump an energy level?

Iris Shim 1E

What does ħ mean in the equation of the Heisenberg's indeterminacy principle? What is the value (and units) of ħ and where does it come from?

Iris Shim 1E

You use the Rydberg Equation (page 7) except you have to multiply the Rydberg equation by Z^2 since the question states that the energy levels differ by a factor of Z^2 from those of hydrogen and the Rydberg equation is used for hydrogen. You use the modified equation to solve for frequency. Then, y...

The negative sign means the electron's energy has decreased, and the energy is released as electromagnetic radiation.
