2-Octyne, also known as methylpentylethyne and oct-2-yne, [1] is a type of alkyne with a triple bond at its second carbon (the '2-' indicates the location of the triple bond in the chain). Its formula is C 8 H 14. [2] Its density at 25 °C and otherwise stable conditions is 0.759 g/ml. [3] The boiling point is 137 °C. [3]

The position of unsaturation is indicated by a numerical locant immediately preceding the "-yne" suffix, or locants in the case of multiple triple bonds. Locants are chosen to be as low as possible. While generally used as a suffix, "-yne" is also used as an infix to name substituent groups that are triply bound to the parent compound.
For esters such as ethyl acetate (CH 3 COOCH 2 CH 3), ethyl formate (HCOOCH 2 CH 3) or dimethyl phthalate that are based on common acids, IUPAC recommends use of these established names, called retained names. The "-oate" changes to "-ate." Some simple examples, named both ways, are shown in the figure above.
Oct-1-en-3-one (CH 2 =CHC(=O)(CH 2) 4 CH 3), also known as 1-octen-3-one or amyl vinyl ketone, is the odorant that is responsible for the typical "metallic" smell of metals and blood coming into contact with skin. [2] Oct-1-en-3-one has a strong metallic mushroom-like odor with an odor detection threshold of 0.03–1.12 μg/m 3 and it is the ...

Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
