Aromaticity

N2 configuration , sp3 hybridization. All atoms within the cycle are sp2 hybridized, number of pi-electrons is 10 (4n+2, n=2), so the cycle is aromatic, the whole molecule is not as it is not cyclic.
S configuration , sp2 hybridization, electrons in the lone pair are pi-electrons. All atoms are sp2 hybridized, molecule is planar and conjugated, number of pi-electrons is 10 (4n+2, n=2), so it is aromatic.
N5 configuration , sp3 hybridization. All atoms within the cycle are sp2 hybridized, number of pi-electrons is 10 (4n+2, n=2), so the cycle is aromatic, while the whole molecule is not as it is not planar.
10) O configuration , sp2 hybridization, electrons in the lone pair are pi-electrons. All atoms are sp2 hybridized, molecule is planar, number of pi-electrons is 8 (4n+2, n=1.5), so it is not aromatic.

The analysis of thymine and its derivatives by electron-ionisation and chemical-ionisation mass spectrometry.
Aromaticity of Thymine is due to the alignment of conjugated double bond and empty orbital of Nitrogens in the ring. Resonance also plays part in stabilizing the molecule. Thymine exists in different tautomeric form but the lactam form is the most stable and the form present in DNA structure. Thymine has the structure of an aromatic heterocyclic ring with two carbonyl attached to 2nd and 4th Carbon. A methyl group is attached to 5th Carbon. The first and third position of the ring is a Nitrogen atom. Both Nitrogen has unoccupied orbital that participates in stabilizing aromatic property of the...

It is also ecofriendly as opposed to the two. Super capacitors are therefore increasingly becoming more probable solutions over both of them in some occasions INTRODUCTION The demand for environmentally friendly energy is ever growing in this globe of rapidly advancing technology. This is mostly so in the developed nations and more so in the scientific frontier. This has led to the technology of capacitors being refined with the aim of storing more energy in devices so that the lesser environmentally friendly storage products like batteries are facing out. This progress has led to the birth of...

A current event of chemistry
In their study, the team first sought to understand the basis of chirality and how it occurs in nature. As an initial understanding, regular triangles are achiral in nature while human hands are chiral. Two achiral objects or molecules can be superimposed on top of each other. Several biomolecules within the body exist in one chiral form and the other form is not present. In their quest to determine how chiral objects are formed, they used achiral particles from which chiral structures are formed spontaneously. They employed the technique of lithography to manufacture millions of achiral...
