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.
Abstract. Hydrocarbons are compounds that are composed solely of carbon and hydrogen atoms. Saturated, unsaturated, and aromatic hydrocarbons are the three principal classes of naturally occurring hydrocarbons.These classes differ in their chemical and metabolic* activities and relative abundances in organisms and sedimentary deposits.bstract.
