Answer to Question #26186 in Organic Chemistry for mymy

Question

C6H6 and C2H2 what is the same and the difference?

Answer 1

The C₆H₆ and C₂H₂ have same empirical formula and percent composition. But C₆H₆ and C₂H₂ are different compounds. Benzene is an organic chemical compound with the molecular formula C₆H₆. Its molecule is composed of 6 carbon atoms joined in a ring, with 1 hydrogen atom attached to each carbon atom. Because its molecules contain only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Acetylene (systematic name: ethyne) is the chemical compound with the formula C₂H₂. It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities.
