www.sigmaaldrich.comPolarizable compounds are compounds composed of carbon and hydrogen, but contain one or more double or triple carbon-carbon bonds. These compounds include alkenes, alkynes, and aromatic (benzene-ring containing) hydrocarbons. Highly polar capillary columns are generally used to separate these compounds. Phase Polarity Based on Compound Polarity
Naming Rules for Organic Compounds
web.viu.caAlkynes - compounds containing carbon-carbon triple bonds 1) Are named and numbered like alkenes. Add "yne" to root name. Aromatic Hydrocarbons - Compounds containing benzene-like rings 1) Benzene is the simplest aromatic compound containing cyclic structure of six carbons with a total of three double bonds. benzene NOT 1,3,5-cyclohexatriene ...
Experiment #3 - Hydrocarbons
employees.oneonta.eduAlkenes, alkynes, aromatic compounds, and cyclic alkanes are unsaturated because hydrogen can be added to them, in theory and usually in practice, making them into acyclic alkanes. Some examples follow. Physical Properties Some molecules carry an electrical charge because there is a difference between

You can construct a large number of models of such molecules of both types (open chain and close chain) keeping in mind that carbon is tetravalent and hydrogen is monovalent. For making models of alkanes, you can use toothpicks for bonds and plasticine balls for atoms. For alkenes, alkynes and aromatic hydrocarbons, spring models can

The alcohol has a higher priority in nomenclature than alkenes, alkynes, alkyl groups and halogen and is given a number lower than any of those groups.

Confirm the aromatic ring by finding peaks at 1600 and 1500 cm-1 and C-H out-of-plane bending to give substitution patterns below 900 cm-1. Confirm alkenes with an absorption generally at 1640-1680 cm-1. C-H absorption between 3000 and 2850 cm-1 is due to aliphatic hydrogens.
