PPT-Alkanes : Saturated Hydrocarbons

Alkenes and Alkynes Aromatic Hydrocarbons Hydrocarbon Derivatives Polymers Natural Polymer Biological Macromolecules Organic and Biological Molecules Organic Chemistry Organic Chemistry The study of carboncontaining compounds and their properties The vast majority of organic compounds contain chains or rings of carbon atoms. Alkanes, alkenes, alkynes and aromatics. Types of Hydrocarbons. Hydrocarbons contain C and H. There are 4 families, alk. anes. only have C-C single bonds, alk. enes. have at least one C=C and alk. ynes. Chapter 22.1 Hydrocarbons. Naming, Drawing, and Properties. They are all around us! . Gasoline, Fuels, and Kerosene are all example of hydrocarbons.. What two elements make up a hydrocarbon?. Hydrocarbons. Orbitals. Natural gas?. Fig. 11.1. Aliphatic Hydrocarbon Structure Comparison. Bonding and Geometry. of Two-Carbon Molecules . 11.1 Structure and Physical. . Properties. Lecture 12. Organic chemistry. What distinguishes organic chemistry from other areas of chemistry?. Origins – compounds from plants and animals. Organic compounds were though to have a “v. ital force” and as such . Organic chemistry:. The study of the compounds of carbon.. 85% of all known compounds are organic.. Carbohydrates, lipids, proteins, enzymes, nucleic acids, hormones, vitamins, and almost all other chemicals in living systems are organic compounds.. Straight chain alkanes will have symmetrical . electronegativities. so they will behave as non-polar molecules. Since ‘like dissolves like’ the alkanes will all be soluble in . eachother. However… since water is polar; alkanes will NOT dissolve in water… think of pouring oil on water. . What is the relationship between the amounts of the alkanes in crude oil and their demand?. Can you think of a way of sorting this problem out?. Methane gas. Octane – found in the petrol fraction. 22.1 Hydrocarbons. Organic Chemistry. includes almost all carbon compounds. Not limited to compounds found in living cells. Hydrocarbon: organic compound made of only hydrogen and carbon atoms. hydrocarbons. Chemistry 11. Ms. McGrath. Classifying Hydrocarbons. Please copy the concept map on page 331 of your textbook.. Hydrocarbons. Consists of . linear. (as opposed to forming rings of carbon atoms) chains of carbon atoms.. The different uses of alkane compounds result from their physical properties, including their solubility and density.. The solid alkanes that make up waxy coatings on fruits and vegetables help retain moisture, inhibit mold, and enhance appearance.. Organic Chemistry. Organic Chemistry. Historically the distinction between inorganic and organic substances was based on whether or not they were produced by living systems. It was believed that some sort of “life force” was needed to synthesize them.. The Structure of Alkanes. Nomenclature of Organic Compounds. Alkyl groups. Numbering the parent carbon chain. The root name is that of the longest continuous carbon chain (. parent carbon chain. ) . Groups attached to the main chain are called . MICHAEL FARADAY (1791-1867). first person to isolate and identify benzene. early benzene uses:. - . decaffeinate . coffee. - antiknock additive . in gasoline. - solvent in chem rxns. now we know benzene is a carcinogen!. Crude oil, hydrocarbons and alkanes. Carbon compounds as fuels and feedstock. Crude. oil. A. finite resource. Consisting. mainly of plankton that was buried in the mud, crude oil is the remains of ancient biomass..
