Consider the following compound, which has been synthesized and characterized:(a) Assuming this molecule is entirely conjugated, do you expect it to be aromatic, antiaromatic, or nonaromatic?(b) Why was this molecule synthesized with three tert-butyl substituents? Why not makethe unsubstituted compound and study it instead?(c) Do you expect the nitrogen atom to be basic? Explain. Why doesn’t nitrogen’s lonepair overlap with the double bonds to give a total of six electrons in the pi system?(d) At room temperature, the proton NMR spectrum shows only two singlets of ratio 1:2. The smaller signal remainsunchanged at all temperatures. As the temperature is lowered to -110 °C, the larger signal broadens and separatesinto two new singlets, one on either side of the original chemical shift. At -110 °C, the spectrum consists of threeseparate singlets of areas 1:1:1. Explain what these NMR data indicate about the bonding in this molecule. How doesyour conclusion based on the NMR data agree with…
Is this molecule aromatic? Why doesn't the pi bond in the benzene ring on the left side not count torward aromaticity?
Aromatic compounds also known as arenes or aromatic are chemical compounds that contain conjugated planar ring system with delocalized pi electron clouds instead of discrete alternating single and double bond. One of the precursor to produce aromatic compounds is arenediazonium.Critize this statement

The unusual molecule below is aromatic and somewhat stable in spite of the positive charge on oxygen. Draw all possible resonance structures to show how the electrons can move about the ring in an uninterrupted circuit.
1. Predict the maximum total number of possible peaks in the 13C NMR spectrum of sesamin (Hint: , keep in mind the molecule’s symmetry when predicting the # of NMR peaks) a. Indicate the number of non-aromatic peaks in the 13C NMR of sesamin b.Indicate the number of aromatic peaks in the 13C NMR of sesamin
Explain how to construct the molecular orbitals of a conjugated cyclic system similar tobenzene and cyclobutadiene. Use the polygon rule to draw the energy diagram, and fillin the electrons to show whether a given compound or ion is aromatic or antiaromatic.
Thoroughly describe what is meant when a compound is considered aromatic. In your answer, provide examples and be sure to discuss how Huckel's Rule applies, and what it means to be anti-aromatic versus non-aromatic. When providing specific examples to demonstrate the requirements that you list, describe the delocalized pi electrons and sp2 hybridization. Lastly, why is benzene so special compared to alkenes like cyclohexene....both are 6-carbon atom cycles so are they chemically similar or not really similar at all?
The 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?
