There are various graphical ways of representing a structural formula, including the simple flat 'Lewis structure' that shows how atoms bond together. A representation called the Natta projection shows molecules in three dimensions, with solid and dotted triangular bonds indicating bonding directions towa...
For example, it is obvious that the simplest surfaces which can be "stretched on the framework" of the structural formula of benzene is a torus; for naphthalene it is a torus with one handle ("knot-shaped"), etc. The boundary surfaces p(x)-c i = 0 for atoms and molecules can thus...

The structure of benzene has been of interest since its discovery. German chemistsJoseph Loschmidt(in 1861) andAugust Kekule von Stradonitz(in 1866) independently proposed a cyclic arrangement of sixcarbonswith alternating single and double bonds. Kekule subsequently modified his structural formula to ...
n where n = 1 or 2; R = H, x = o-OH; R = CH3; x = p- OCH3, p-OH, p- Br, p- F, p- Cl have been synthesised by the reactions of phenylarsenic(III) dichloride with the sodium salt of the corresponding ligand in 1:1 and 1:2 molar ratios in refluxing benzene solution...

This observed higher affinity of Quercetin amongst other flavonoids could be due to the differences in molecular structure of the flavonoids. Although all of these flavonoids have similar ring structure consisting of a heterocyclic pyrane ring (C) that links two benzene rings (A and B)19, the ...

A series of octahedral Ru(III), Rh(III) and Ir(III) complexes have been prepared with tetradentate Schiff bases derived by condensing isatin with 1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane, 1,2-diaminobenzene and 1,3-diaminobenzene. The obtained complexes were characterized on ...
