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.
Cycloalkanes These are hydrocarbons that have one or more carbon rings. These rings have hydrogen atoms attached to it. Aromatic hydrocarbons These hydrocarbons have a stable structure and they have one aromatic ring. An example of one of the simplest aromatic hydrocarbons is benzene.These are also known as Arenes.ycloalkanes These are hydrocarbons that have one or more carbon rings.
