Re: addition reactions

It is also important to note that addition reactions will only occur with carbons who have multiple bonds and will normally not affect any other part of the molecule

Re: The Number of Intermediates for Electrophilic Addition

When considering electrophilic addition reactions it is important to distinguish between reactants that are in transitions phases and intermediated. Those shown in transition phases are in the process of forming and breaking bonds while intermediates a substances that are formed in one reaction as t...

Re: Irreversible vs. Reversible

I find it helpful to define reversible as "perfect." If a process is reversible it will function perfectly at a constant rate meaning that the reverse could be done the same way.

Re: Enthalpy sign changes

Using bond enthalpies to calculate the change in enthalpy we know that when bonds are formed they release energy and will have a negative (-) value. Basically, change the products to negative and keep the reactants positive. Ref. page 16 of the course reader.

Question 1.33 on the homework

On part C of problem 33 the answer key asks us to consider the kinetic energy of the electron but I was wondering why we couldnt find the wavelength directly form the energy calculated earlier.
