Many works of fiction have incorporated into their world the existence of beverages or drinks – liquids made for popular consumption – which may create a sense of the world in which the story takes place, and in some cases may serve to advance the plot of the story.
Allyl alcohol is converted mainly to glycidol, which is a chemical intermediate in the synthesis of glycerol, glycidyl ethers, esters, and amines. Also, a variety of polymerizable esters are prepared from allyl alcohol, e.g. diallyl phthalate. [5] Allyl alcohol has herbicidal activity and can be used as a weed eradicant [9]) and fungicide. [8]
Although the presence of an allylic alcohol does lead to increased stereoselectivity, the rates of these reactions are slower than systems lacking alcohols. However, the reaction rates of substrates with a hydrogen bonding group are still faster than the equivalent protected substrates. This observation is attributed to a balance of two factors.
Golden Age of Science Fiction — a period of the 1940s during which the science fiction genre gained wide public attention and many classic science fiction stories were published. New Wave science fiction — characterised by a high degree of experimentation, both in form and in content.
A site adjacent to the unsaturated carbon atom is called the allylic position or allylic site. A group attached at this site is sometimes described as allylic. Thus, CH 2 =CHCH 2 OH "has an allylic hydroxyl group". Allylic C−H bonds are about 15% weaker than the C−H bonds in ordinary sp 3 carbon centers and are thus more reactive.
"A science fiction story is a story built around human beings, with a human problem, and a human solution, which would not have happened at all without its scientific content." [13] Basil Davenport. 1955. "Science fiction is fiction based upon some imagined development of science, or upon the extrapolation of a tendency in society." [14] Edmund ...
As an emerging genre, slipstream has been described as nonrealistic fiction with a postmodern sensibility, exploring an awareness of societal and technological change and psychological breakdown previously shown by science fiction authors during the time of postmodernism, as well as poets and experimental authors in modernism.
Literary fiction is often used as a synonym for literature, in the exclusive sense of writings specifically considered to have considerable artistic merit. [6] Literary fiction is commonly regarded as artistically superior to genre fiction, the latter being a form of commercial fiction written to provide entertainment to a mass audience. [7] [8 ...
