What is the density of biphenyl?
1.04 g/cm³Biphenyl / Density
What is the molar mass of biphenyl?
154.21 g/molBiphenyl / Molar mass
Is biphenyl soluble in ethanol?
Soluble in ethanol, ethyl ether; very soluble in benzene, carbon tetrachloride, carbon disulfide, and methanol.
Is biphenyl A carcinogen?
Kidney effects have been observed in chronically (long-term) exposed animals. EPA has classified biphenyl as a Group D, not classifiable as to human carcinogenicity.
Is biphenyl soluble in n hexane?
The ionic and very hydrophilic sodium chloride, for example, is not at all soluble in hexane solvent, while the hydrophobic biphenyl is very soluble in hexane.
Is biphenyl neutral?
Biphenyl is a neutral molecule and fairly non-reactive due to lack of functional group. However, biphenyl participates in many of the reactions that are typical for benzene, for example, substitution reactions upon treatment with halogens in the presence of a Lewis acid.
Why is biphenyl insoluble in methanol?
Because biphenyl lacks the polar functional groups, it was only partially soluble in methyl alcohol. Because biphenyl is nonpolar and methyl alcohol is intermediately polar, only a small amount of biphenyl can dissolve in methyl alcohol.
What is the point group of biphenyl?
D 2 point group
18 In the gas phase, biphenyl in its lowest-energy conformation belongs to the D 2 point group.
What is the functional group of biphenyl?
Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl.It has a distinctively pleasant smell. Biphenyl is an aromatic hydrocarbon with a molecular formula (C6H5)2.
Is biphenyl aromatic or non aromatic?
aromatic
Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen (the site at which it is attached) may use the prefixes xenyl or diphenylyl.It has a distinctively pleasant smell. Biphenyl is an aromatic hydrocarbon with a molecular formula (C6H5)2.
Is biphenyl aromatic or Antiaromatic?
Biphenyl has 12 π-electrons and according to Hückel’s rule, it should not be aromatic because 12≠4n+2, but it nevertheless is aromatic.
What is the IRIS program EPA?
Integrated Risk Information System. EPA’s mission is to protect human health and the environment. EPA’s IRIS Program supports this mission by identifying and characterizing the health hazards of chemicals found in the environment. Each IRIS assessment can cover a chemical, a group of related chemicals, or a complex mixture.
How many ppm of biphenyl are in a rat’s diet?
Umeda et al. (2002) exposed F344 rats (50/sex/group) to biphenyl in the diet for 2 years at concentrations of 0, 500, 1,500, or 4,500 ppm (corresponding to doses of 36.4, 110, and 378 Integrated Risk Information System (IRIS) U.S. Environmental Protection Agency Chemical Assessment Summary National Center for Environmental Assessment
What is an iris assessment?
Is the nervous system a target of oral biphenyl toxicity?
The 2-year oral bioassays in rats and mice (Umeda et al., 2005; Umeda et al., 2002) did, however, include daily observations for clinical signs and histopathological examination of nervous system tissues. No nervous system effects were reported, suggesting that the nervous system is not a sensitive target of oral biphenyl toxicity.
