Document Summary
4. 3: alkanes hydrocarbon with single bonds, cycloalkanes all or some alkanes are arranged in ring, alkane formula is cnh2n+2, cycloalkane is c(n)h2(n, primary source of alkane is petroleum with most alkanes and aromatic compounds, contain small amounts of oxygen, nitrogen, and sulfur, petroleum accumulated from dead microorganisms settled at the bottom of the sea as microbiological remain transformed into oil by heat radiating, hydrocarbons are found in outer space; asteroids and comets contain variety of organic compounds, alkanes and cycloalkanes have sp3 hybridization, this is known as tetrahedral sp3 hybridization, alkanes are not always straight zigzagged (rotations can create large, they are all un branched each carbon within a chain is bonded to no more than differences) two other carbon atoms, contain only primary and secondary carbon atoms (not bonded to more than 2, branched chains are carbons bonded to 2 or more other carbon atoms, examples are isobutene (c connected to 3 other methyl groups)
