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.
hydrocarbon. an organic compound that contains carbon and hydrogen only. alicyclic hydrocarbon. one that has cyclic structure and aliphatic properties. aliphatic hydrocarbon. one that does not contain an aromatic ring.aromatic hydrocarbon. one that has cyclic structure and a closed conjugated system of double bonds.licyclic hydrocarbon. one that has cyclic structure and aliphatic properties. aliphatic hydrocarbon. one that does not contain an aromatic ring. aromatic hydrocarbon. one that has cyclic structure and a closed conjugated system of double bonds.
