When an NMR spectrum is taken of the molecule below, there is the expected 5H in the aromatic region, triplet (3H) and quartet (2H) upfield of the aromatic region.
After adding a drop of acidic D2O, the spectrum changes to one that just has 5H aromatic protons and an upfield 3H singlet. What happens? Explain with mechanisms step by step and include charges and lone pairs of all compounds involved.
Can you please check my work on the following ochem reaction scheme and let me know if it is correct or what is wrong...

Draw two separate Frost circle (polygon-in-a-circle) diagrams for both the cycolopropenyl cation and anion shown below. Label the respective orbitals as bonding or anti-bonding (do not show shaded orbital pictures, only show the MO energy levels and -electrons). In both cases provide a rationale indicating whether the compound is aromatic, anti- aromatic, or non-aromatic. H E E Harrow_forwardThe instructions were to define if the molecule was aromatic or antiaromatic. If the element (such as N or O) has a double bond directly on it, then its lone pair doesn't count in the conjugation system; if there's a single bond, then its lone pair is counted. I counted the electrons on the lone pairs, and since the total was 6 e-, I labeled it as aromatic. was this correct?arrow_forward
