The American cockroach (Periplaneta americana) is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, [1] though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary. [2]
In other less formal contexts, an alcohol is often called with the name of the corresponding alkyl group followed by the word "alcohol", e.g., methyl alcohol, ethyl alcohol. Propyl alcohol may be n-propyl alcohol or isopropyl alcohol, depending on whether the hydroxyl group is bonded to the end or middle carbon on the straight propane chain. As ...

English: This is a diagram showing the formation of a secondary alcohol via reduction and hydration. The drawing was done in ACD/ChemSketch v12.01 (using standard ACS structure drawing style) and exported as a Windows Metafile (WMF). The image was converted to SVG using Inkscape v0.48.1 to yield a vector graphics version.
Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), contain stereocenters, and are therefore chiral and optically active. The most important amyl alcohol is isoamyl alcohol , the chief one generated by fermentation in the production of alcoholic beverages and a constituent of fusel oil .
These groups are found in many compounds. Propenyl compounds are isomeric with allyl compounds, which have the formula CH 2-CH=CH 2. The three common precursors to lignin are derivatives of propenylbenzene: paracoumaryl alcohol (1), coniferyl alcohol (2) and sinapyl alcohol (3).
The common roach is found throughout Europe except for the area around the Mediterranean, and its distribution reaches eastward into Siberia. Eastern Europe and Asia have several subspecies, some with an oceangoing life cycle living around the Caspian and Black Seas. [5]
