as noted above, and second that we have names for simple alkyl groups that may be attached to the chains. Examples of some commonalkyl groupsare given in the following table. Note that the “ane” suffix is replaced by “yl” in naming groups. The symbolRis used to designate a generic ...

these examples, simple haloalkanes are named according to the specific halogen element (F, Cl, Br or I) in the molecule and the number of carbon atoms (using the same system of naming as applies toalkanes).More information about structures, names and classification of haloalkanes follows ...
E.g. 5 carbons = pentane C5H12 6 carbons = hexane C6H14 7 carbons = heptane C7H16 8 carbons = octane C8H18 9 carbons = nonane C9H20 10 carbons = decane C10H22 carbon hydrogen pentane Names of alkanes Alkanes all have very similar structures. They all consist of carbon and ...

What follows are the names and formulas for the first eight normal, or unbranched, alkanes. Note that the first four of these received common names before their structures were known; from C5onward, however, they were given names with Greek roots indicating the number of carbon at...
Alkanes:Alkanes exist as gases, liquids and solids. Methane, ethane, propane and butane are gases at room temperature. The unbranched structures of hexane, pentane and heptane are liquids. Alkanes which have a higher molecular weight are solids. ...

propellane and bicyclo [3,2,1]-octane, have two rings that share more than one C-C bond. Still other cycloalkanes are polycyclic (poly means “many”). Some of these structures are very highly strained, given the C-C-C bond angles; many are chemical curiosities synthesized in the ...
