Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform -like odour that can be detected at low levels.
CCL4 is a polypeptide chain with a molecular weight of approximately 8-10 kDa [10] arranged in a three-dimensional structure in the form of as symmetrical homodimer. Monomeric subunits in their secondary structure composed by a triple-stranded antiparallel sheet form in a Greek key structure on top of which lies an α-helix.
Partial atomic charges can be used to quantify the degree of ionic versus covalent bonding of any compound across the periodic table. The necessity for such quantities arises, for example, in molecular simulations to compute bulk and surface properties in agreement with experiment.
For example, methyl chloride CH3Cl is an organic compound with a covalent C−Cl bond in which the chlorine is not an anion. Other examples of covalent chlorides are carbon tetrachloride CCl4, sulfuryl chloride SO2Cl2 and monochloramine NH2Cl.
Transition metal chloride complex. Octahedral molecular geometry is a common structural motif for homoleptic metal chloride complexes. Examples include MCl 6 (M = Mo, W), [MCl 6] − (M = Nb, Ta, Mo, W, Re), [MCl 6] 2- (M = Ti Zr, Hf, Mo, Mn, Re, Ir, Pd, Pt), and [MCl 6] 3- (M = Ru Os, Rh, Ir). In chemistry, a transition metal chloride complex ...
A solubility chart is a chart describing whether the ionic compounds formed from different combinations of cations and anions dissolve in or precipitate from solution.
Salt (chemistry) The crystal structure of sodium chloride, NaCl, a typical salt. The purple spheres represent sodium cations, Na +, and the green spheres represent chloride anions, Cl −. The yellow stipples show the electrostatic forces. In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively ...
Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded ...
