Re: Dipoles Cancelling Out

DarrenKim_3G wrote:I believe cancelling out has to do with the symmetry of a molecule. For example C2Cl4 has no net dipole moment because the molecule is symmetric so the moment cancels out

When you say symmetric what does that exactly refer too, perhaps the shape of the element?

Re: Boiling Point

How can we determine between elements which will have a higher boiling point?

Re: Polarity

Is there another way besides drawing out an element to determine the polarity?

Re: HYDROGEN BONDING

In terms of covalent, ionic, and hydrogen bonds which is the strongest and why? I would think ionic but I can see how hydrogen bonds are stronger since they are easily attracted to high electronegative elements.

Re: Dipole Moment

When Lavelle was drawing the water molecule to show the dipole moment why did he put the arrows pointing toward the oxygen? Is it because of oxygen's higher electronegativity?

Adding on, Oxygen has a high electronegativity so having a formal charge of 2+ is not ideal.

Re: Delocalization vs. Resonance

So in terms of delocalization can we say this occurs when atoms form bonds with each other because in a way they are spreading out their electrons through sharing them?

Ionic Bonds

Just for clarification, ionic bonds are formed between elements that are further from each other due to a substantial difference in their electronegativity?

Heisenberg Constant

Why is that when we learned about the Heisenberg uncertainty principle the principle was h/4*pi but in the textbook, they referred to the constant as h/2.

Exceptions to the Octet Rule

I remember that there were certain exceptions to the Lewis structure in regards to the octet rule, however, I don't understand the logical/reason behind it. Can someone please explain?

Re: Wavelength Plausibility

I remember in the lecture the slides said that visible light can be seen from 700nm (Red) to 400nm (Violet) but in the picture from the slides it went up to 720 nm. So, basically my question is if visible light ranging from 700 nm to 400nm or from 720nm to 400nm.
