organic chemistry-reaction mechanisms
1. The problem statement, all variables and given/known data
In pyrrole the electron density is maximum on which carbon atom? [IMG]so if the numbering starts from nitrogen, the carbon on the right side of nitrogen let it be numbered as 2 and the next one as 3 and so on... which of the following options will have the carbons of maximum electron density? a) 2,3 b) 3,4 c)2,4 d)2,5.
2. Relevant equations
electron density will be maximum on that carbon in which there is a maximum mesomeric or resonance effect.
3. The attempt at a solution
[IMG] here the -ve sign on the carbon atoms represent that the electron is crowded there. so i could see that from the resonance structures all of the carbon atoms were electron crowded for some time among the resonants.. so which option will be the apt? and how to identify it? if inductive effect should also be considered, isn't it is less significant mesomeric effect?
