benzene molecular weight
[Note: A solid below 42°F.] These reactions are versatile and widely used to prepare derivatives of benzene. What benzene is . In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. This FAD-binding protein … Note that rounding errors may occur, so always check the results. Author of, Benzene is the smallest of the organic aromatic hydrocarbons. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Can you explain this answer? Benzene dissolves only slightly in water and will float on top of water. Benzene. The carbon atoms are represented by a corner that is bonded to other atoms. The vapour pressure of the solution is 600 mm Hg. This value is exactly halfway between the C=C distance (1.34 Å) and C—C distance (1.46 Å) of a C=C—C=C unit, suggesting a bond type midway between a double bond and a single bond (all bond angles are 120°). Modern bonding models (valence-bond and molecular orbital theories) explain the structure and stability of benzene in terms of delocalization of six of its electrons, where delocalization in this case refers to the attraction of an electron by all six carbons of the ring instead of just one or two of them. Online calculator, figures and table showing density and specific weight of benzene, C 6 H 6, at temperatures ranging from 5 to 325 °C (42 to 620 °F) at atmospheric and higher pressure - Imperial and SI Units Density, ρ, has units typically [kg/m3] or [lb/ft3], and is defined by the ratio of the mass to the volume of a substance: ρ = m/V Department of Health and Human Services. Policies. The Corporation handles the largest network of petrol and diesel stations in the country. The next largest use of benzene is in the preparation of phenol. Convert grams Benzene to moles or moles Benzene to grams. Browse the list of Please select which sections you would like to print: Corrections? If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. In 1845 German chemist A.W. We use the most common isotopes. It is highly toxic and is a known carcinogen; exposure to it may cause leukemia. National Library of Medicine. Other uses include the preparation of aniline (for dyes) and dodecylbenzene (for detergents). It contains sigma bonds (represented by lines) and regions of high-pi electron density, formed by the overlapping of. The structure has a six-carbon ring which is represented by a hexagon and it includes 3-double bonds. Benzene weighs 878.65 kg/m³ (54.85233 lb/ft³), melting and boiling points, molecular formula and weight, molar volume, CAS RN and reference information Use this page to learn how to convert between grams Benzene and mole. (1,7) Benzene has a sweet odor with an ASTDR reported odor threshold of 1.5 ppm (5 mg/m 3). Ethylbenzene is produced in on a large scale by combining benzene and ethylene in an acid-catalyzed chemical reaction: C 6 H 6 + C 2 H 4 → C 6 H 5 CH 2 CH 3. As a result, the hydrogenation of benzene occurs somewhat more slowly than the hydrogenation of alkenes (other organic compounds that contain carbon-carbon double bonds), and benzene is much more difficult to oxidize than alkenes. Molecular Weight Search Help Search options (step 1) (Back to search) You may search for species based on molecular weight values in two ways: Specify a single value; the system will search for values within 0.5 units of this value. At one time, benzene was obtained almost entirely from coal tar; however, since about 1950, these methods have been replaced by petroleum-based processes. von Hofmann isolated benzene from coal tar. As it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene (C6H6), simplest organic, aromatic hydrocarbon and parent compound of numerous important aromatic compounds. The structural representation of benzene is as shown in the figure below. National Institutes of Health. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. At one time, benzene was obtained almost entirely from coal tar; however, since about 1950, these methods have been replaced by petroleum-based The SI base unit for amount of substance is the mole. IndianOil’s cross-country network of crude Oil and product pipelines is spread over 10,000 Km. 9011-11-4 - ZAKVZVDDGSFVRG-UHFFFAOYSA-N - Benzene, ethenyl-, polymer with (1-methylethenyl)benzene - Similar structures search, synonyms, formulas, resource links, and other chemical information. In benzene, the atoms are hydrogens. 12.0107*6 + 1.00794*6. The question isn't framed very well. The double bonds within this structure are mainly separated by a single bond… A non-volatile solid weighing 2.175 g is added to 39.0 g of benzene. As a result, there are strict controls on benzene emissions. ›› Benzene molecular weight. Calculate the molecular weight Let us know if you have suggestions to improve this article (requires login). Summary: This gene is a member of the NAD(P)H dehydrogenase (quinone) family and encodes a cytoplasmic 2-electron reductase. Molecular Formula C 6 H 6; Average mass 78.112 Da; Monoisotopic mass 78.046951 Da; ChemSpider ID 236 Our editors will review what you’ve submitted and determine whether to revise the article. Benzene C6H6 Molar Mass, Molecular Weight. Benzene is a chemical that is a colorless or light yellow liquid at room temperature. In 2012, more than 99% of ethylbenzene was produced in this way. A common request on this site is to convert grams to moles. The chemical formula for benzene is C6H6, i.e it has 6 hydrogen- H atoms and six-carbon atoms and has an average mass of about 78.112. The atomic orbitals that provide the so-called basis set for the molecular orbitals (i.e., those from which the MOs are constructed) are the carbon 2, …the broad 254-nanometre transition in benzene (C. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. In benzene, acetic acid molecules get dimerised.
