This means the species a binomial name refers to can be clearly identified, as compared to the common names of species which are usually different in every language. [6] However, establishing that two names actually refer to the same species and then determining which has priority can sometimes be difficult, particularly if the species was ...
A cyclic ether and high-boiling solvent (b.p. 101.1 °C). Tetrahydrofuran (THF) A cyclic ether, one of the most polar simple ethers that is used as a solvent. Anisole (methoxybenzene) An aryl ether and a major constituent of the essential oil of anise seed. Crown ethers: Cyclic polyethers that are used as phase transfer catalysts. Polyethylene ...
Bear habitats are generally forests, though some species can be found in grassland and savana regions, and the polar bear lives in arctic and aquatic habitats. Most bears are 1.2–2 m (4–7 ft) long, plus a 3–20 cm (1–8 in) tail, though the polar bear is 2.2–2.44 m (7–8 ft) long, and some subspecies of brown bear can be up to 2.8 m (9 ...
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
Ursus is a genus in the family Ursidae that includes the widely distributed brown bear, [3] the polar bear, [4] the American black bear, and the Asian black bear. The name is derived from the Latin ursus , meaning bear .
The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ethoxymethane). If the oxygen is not attached to the end of the main alkane chain, then the ...
Polari words spread, as the language itself faded. On March 7, 1963 a radio show called “Round the Horne” premiered on the BBC. In Episode 4, the popular comedy program introduced Sandy and ...
As is typical of ethers, dipropyl ether may slowly form explosive organic peroxides over long periods in storage. [2] Antioxidants such as butylated hydroxytoluene are often added to ethers to prevent this process. [4] Due to the shock and light sensitive nature of organic peroxides, dipropyl ether should never be boiled or evaporated to dryness.
