More dramatically, a long-chain hydrocarbon like squalene (C 30 H 62) has a viscosity an order of magnitude larger than the shorter n-alkanes (roughly 31 mPa·s at 25 °C). This is also the reason oils tend to be highly viscous, since they are usually composed of long-chain hydrocarbons.
The properties of deuterated benzene are very similar to those of normal benzene, however, the increased atomic weight of deuterium relative to protium means that the melting point of C 6 D 6 is about 1.3 °C higher than that of the nondeuterated analogue. The boiling points of both compounds, however, are the same: 80 °C. [2]
Divinylbenzene (DVB) is an organic compound with the chemical formula C 6 H 4 (CH=CH 2) 2 and structure H 2 C=CH−C 6 H 4 −HC=CH 2 (a benzene ring with two vinyl groups as substituents).It is related to styrene (vinylbenzene, C 6 H 5 −CH=CH 2) by the addition of a second vinyl group. [2]
For many substances, the formation reaction may be considered as the sum of a number of simpler reactions, either real or fictitious. The enthalpy of reaction can then be analyzed by applying Hess' law, which states that the sum of the enthalpy changes for a number of individual reaction steps equals the enthalpy change of the overall reaction.
Allylbenzene or 3-phenylpropene is an organic compound with the formula C 6 H 5 CH 2 CH=CH 2. It is a colorless liquid. The compound consists of a phenyl group attached to an allyl group. Allylbenzene isomerizes to trans-propenylbenzene. [3] In plant biochemistry, the allylbenzene skeleton is the parent (simplest representation) of many ...
