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.
A hydrocarbon chain is like a pearl necklace made of carbon atoms. However, each carbon pearl is adorned with one or up to three hydrogen atoms. Understanding the chemical properties of a carbon atom and the nature of covalent bonding will clarify why hydrocarbons take on the forms that they do.tring of Pearls. A hydrocarbon chain is a chain of carbon atoms linked by covalent bonds, like a pearl necklace. A covalent bond unites two atoms when they share electrons. Individual carbon atoms have four valence electrons, which form covalent bonds and are located on the outermost energy level of the atom.
