tertiary vs neo

I was wondering what the difference between a tertiary carbon substituent and a neopentane substituent are, as both create a plus-sign shape when drawn with the line model. Also, when do we use each, as I know that we do use iso- to describe substituents but in the practice problems, they seem to us...

Re: winter 2012 midterm question 3A

Why do you consider only 2 bonds for the three spaces? Can you go into more depth for the explanation for why W=3 for BH2F?

Finding Conjugate Acids and Bases

When you're trying to find a conjugate acid or a conjugate base of a molecule that has multiple H's, how do you know which one to take away/add to?

For example, finding the conjugate base of CH3COOH?

Kc vs Partial Pressure

For an equation with both gases and aqueous reagents and products, how would you convert between the partial pressure (which you use for gases) and the concentration (used for aqueous solutions)?

Re: Bond Lengths and Lewis Structures

Yes, for bond lengths you do look for whether there are single, double, or triple bonds. To find these, you draw Lewis structures and count formal charges. Formal Charge = (V - ( L + B/2)). For this example, SO2 and SO3 have double bonds (you can discover this through formal charge) and SO3 2- has o...

Dipole Moment Arrows

When you draw a dipole moment, the "old" way of signifying the dipole moment was an arrow pointing towards the negative charge. The more modern way to note a dipole moment is an arrow pointing towards the positive charge. Why did this change? And what do the arrows signify (if they signify...

Electron Affinity vs Ionization Energy

If the trends for electron affinity and ionization energy are the same (as in both decrease down a group and increase across a period), how do we differentiate when to use each and when do we use ionization energy to describe an atom vs electron affinity?

Wave-Particle Duality/ Intensity of Radiation

In the textbook, it says "In the wave model, the intensity of the radiation is proportional to the square of the amplitude of the wave. In the particle model, intensity is proportional to the number of photons present at each instant. " So for the wave-particle duality, which is the accept...
