Both naphthalene and azulene have 10 pie electrons and are aromatic. Pentalene is apparently antiaromatic and is unstable even at -100 degrees C. Heptalene has been made but it adds bromine, it reacts with acids, and it is not planar. Is Huckle's rule applicable to these compounds? If so, explain their lack of aromaticity.
Attached to this problem is an IR spectra of an unknown which is known to be a solid and after a few solubility and other test I think that it is a carboxylic acid. I needed some one else to verify. Please label peaks and give the name of compound.
The formation of an azo compound is a slow reaction, but that rate can be increased by raising the pH of the solution. Why is this necessary? In other words, how does the pH of the solution affect the reactivity of the N,N-dimethylaniline reagent.
