1. Lithiation of arylethers

Is it possible someone can explain the point of doing this, I am having a really hard time grasping the concept. For example if I have anisole and I use butyl litium as a reagent, my understanding is that it will behave like a base and deprotanate the ring, resulting in a lithium bonded to the...
2. Is it okay to use dot/cross for free radical rxns

I'm learning about various radical reactions, the thing is I'm still getting my head around 'half arrow' mechanisms. However for some reason the dot and cross model for these types of reactions is really intuitive and works great for my understanding. Is this a dangerous path to go down, to work...
3. Time evolution problem.

1. Homework Statement A box containing a particle is divided into a left and right compartment by a thin foil. The two orthonormal base kets |L> and |R> stand for the particle being in either the left or the right compartment, respectively. Hence, any state ket in our system can be...
4. Help with Operators written as components.

I would appreciate if someone could set me straight here. I understand if I have an arbitrary operator, I can express it in matrix component notation as follows: Oi,j = <vi|O|vj> Is it possible to get a representation of the operator O back from this component form. I'm more interested...
5. Derivation of 1st london equation.

This is my first time posting here, I apologize if this is the wrong place to ask such a question. In my book I have the following London equation written (1st) for a superconductor: E=μ0λ2L∂J/∂t where: λ2L is the london penetration depth. My understanding is that it can be derived...
