Simply by observing the existence of the Cherenkov radiation from a particle, one can determine its relative velocity with respect to the light speed in medium. Knowing that, one can determine the particle momentum.
It is a ring formed carbon skeleton. The smallest possible cyclic hydrocarbon is cyclopropane (triangular C3H6) together with cyclobutane both being rather unstable (degration to linear propene and 1-butene). Five and six membered rings are quite common.
Organic compounds that contain only carbon and hydrogen are hydrocarbons, which differ from one another by the number of carbon and hydrogen atoms they contain. The simplest hydrocarbon is methane, CH 4, with only one carbon per molecule.Methane is the main component of natural gas. The hydrocarbon octane, C 8 H 18, has eight carbons per molecule and is a component of gasoline. The hydrocarbon polyethylene contains hundreds of carbon and hydrogen atoms per molecule.rganic compounds that contain only carbon and hydrogen are hydrocarbons, which differ from one another by the number of carbon and hydrogen atoms they contain.
