Part of what makes a metal what it is is its propensity to lose the electrons in its outer shell and become an ion, which is a charged particle. Ions prefer to coalesce into solid lattice structures. Covalent molecules, on the other hand, more often form liquids or gases. When Is a M...
Several types of a compound are found in nature some are aromatic while some aliphatic. The types of compounds that follow Huckel's rule and are planar in nature can be considered aromatic compounds.Answer and Explanation: The given compound is para-bromotoluene. The chemical formula of para-...
What makes a chromophore?with conjugated polymers may arise fromthe chromophores themselves3. This hasdirect consequences for devices such asLEDs and solar cells: optimizing theirstability and performance will requirecontrol over the conformation of individual chromophores, rather than the arrangement of ...
N-Phenylsydnone, so-named because it was first studied at the University of Sydney, Australia, behaves like a typical aromatic molecule. Explain, using the Huckel 4n + 2 rule. What does GP stand for? What is the purpose of a moderator in a reactor?
The arrangement of atoms or molecules in a crystal, represented as a repeating arrangement of points in space, each point representing the location of an atom or molecule; called also crystal lattice and space lattice. Crystal A person's eye. Lattice To make a lattice of; as, to lattice ti...
Fig. 2, a and b). A b-sandwich is two planar b-sheets face-to-face (see Fig. 2 c). For example, in the fibrillar state the Ab molecule is a V-shaped b-hairpin comprised of two b-strands. In amyloid fibrils, the b-sandwich is stabilized by H-bonds parallel to the fi...
Cancer biology is addressed by the a priori choice of a suitable tracer molecule to probe the existence of a suspected disease and to further phenotype it. The availability of molecular probes and the choice of the most appropriate tracer will be the focus of a companion contribution to this ...
3 pairs of bonding electrons and one pair of non-bonded electrons. As we’ve seen, the ideal geometry for arranging four pairs of electrons is tetrahedral, which makes the hybridization of the central atom sp3. This leaves the molecule with a “piano stool” arrangement of atoms about the ...
delocalization of theπelectrons in the ring and there should be(4n+2)π(where n is a whole number) electrons present in the ring. Answer and Explanation:1 The chemical compound are said to be aromatic if they contain one or more planar rings of atoms which are joined by two different ...
Explain the important points regarding the molecule of 'Benzene'. Why hexane dissolved in toluene? What is the purpose of an emulsifier? Why is benzene less reactive 1,3,5-cyclohexatriene? How would you synthesize the following substances starting from benzene? (a) (b) (c) Why is pyridine...
