WebThese branched alkanes are isomers of straight-chain alkanes having the same number of C atoms. However, they are different compounds with different physical and chemical properties. ... For example, in the alkane shown here, the longest chain is five C atoms long, so it is a pentane. There is a one-carbon substituent on the third C atom, so ... WebA continuous (unbranched) chain of carbon atoms is often called a straight chain even though the tetrahedral arrangement about each carbon gives it a zigzag shape. Straight-chain alkanes are sometimes called normal alkanes, and their names are given the prefix -. For example, butane is called -butane. We will not use that prefix here because it ... storm door for door with sidelight

WebHere, we will add some steps to the procedure so you can name branched hydrocarbons. First, given the structure of an alkane, identify the longest continuous chain of C atoms; this is known as the parent chain. Note that the longest chain may not be drawn in a straight line. The longest chain determines the parent name of the hydrocarbon. WebLike alkyl groups, alkanes can also have common names. Common, or “trivial” names are rarely used for straight chain alkanes, but are frequently used for branched alkanes.
