Is the elimination reaction between 1 1 dibromo cyclopropane and phenyl lithium feasible in alkaline medium (and some heat)

I found this question in one of my question papers for the JEE , My sir gave me an explanation that due to resonance between lone pairs of the bromide and π bond formed. This reasoning doesn’t seem to be satisfying because of the cyclopropyl ring strain which is not lost even at the end […]

Why do some molecules show non-symmetric absorption and emission bands?

I’m looking at a molecule of [Ru(bpy)3]2+ in water and the absorption and emission bands are not symmetrical. I want to know why the mirror image rule doesn’t apply here. Is this because of the MLCT, is this something to do with the solvent? Are there more likely to be processes involving non-radiative decay? I’m […]

Moller Plesset Theory- MP2 correction

I have a molecule LiBH2 with C2V point group. I used 3-21G basis set and obtained RHF coefficients and symmetry of orbitals. I wish to find the set of orbitals (a,b,i,j)( where a and b are occupied and i and j are virtual oritals) that contribute to MP2 correlation energy. That is, in the process […]

Learning to select a subgraph via reinforcement learning?

I have the following problem: I am given a graph with a lot (>30000) nodes. Nodes are associated with a low (<10)-dimensional feature vector, and edges are associated with a low (<10)-dimensional feature vector. In addition, all nodes start out having the color white. At every time step until completion, I want to select a […]

If we append an element to a list, how is preserving the immutability of the list in Scala? Should not a new list be made? In java if you add a letter to be the first character, then a new String would be made, and strings are immutable in Java. What is the reason for […]
