Our mission is to liberate knowledge. Privacy Policy Strong, stable bonds between carbon atoms produce complex molecules containing chains, branches, and rings. Identify the hydrocarbon. TOS In recent years, NMR spectroscopy has lead to a revolution in the practice of diagnostic medicine. Registered Member. These categories have a large influence on both the reactivity and physical properties of organic compounds. Find the longest carbon chain and number the carbons in the longest chain In fact, it does a little good to your engine by increasing the flame speed. A hydrocarbon C 5 H 10 does not react with Chlorine in dark but it gives a single monochlorocompound C 5 H 9 Cl in bright sunlight.

It is an alkane and will have the suffix -ane. About. Hydrocarbons can be classified as either aromatic or aliphatic compounds, depending on the presence of a benzene ring. Freon-12: The chlorofluorocarbon compounds of methane and ethane are collectively known as ferons. Thus for an alkene containing not carbon atoms in its molecule, the number of hydrogen atoms will be 2n, i.e., the general formula of alkenes is CnH2n.
