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.
The study of hydrocarbons is a very large part of organic chemistry. Hydrocarbons are molecules containing only the elements carbon and hydrogen in the form of chains.Hydrocarbons can be classified into two categories based on the presence of a benzene ring, a circular type of hydrocarbon.he study of hydrocarbons is a very large part of organic chemistry.
