Hydrocarbons contain only hydrogen and carbon. Which of the following is not a class of pure hydrocarbons? (a) Alkynes (b) Alcohols (c) Alkenes (d) Alkanes. Name four oxidizing agents that are commonly used in organic chemistry. What is the functional group for an alkane?
Sulphatable organic compounds containing active hydrogen include primary, secondary and tertiary alcohols including methyl, lauryl, benzyl and furfuryl alcohols; polyhydric alcohols including glycol, glycerol and sugars; phenols e.g. resorcinol; non-tertiary amines e.g., dimethylamine, aniline, benzidine,...
aOrganic compounds that are known to be contaminates of indoor environments include a large variety of aliphatic hydrocarbons, aromatic hydrocarbons, oxygenated hydrocarbons (such as aldehydes, ketones, alcohols, ethers, esters, and acids), and halogenated hydrocarbons (primarily those containing chlorine...
aThe alcohols appeared to be determined with medium r2 values (0.39) in two different regions: 619 nm (orange color) for methanol and 1565 nm for ethanol, while the pH showed the highest single relationship (0.70) in the visible spectrum at 663 nm, i.e., in the far-red. 酒精看上去确...
Epoxy compounds are a very important class of organic chemical raw materials and intermediates. This type of compound molecule contains a three-membered oxygen ring structure. Under the action of an acidic or alkaline catalyst, the three-membered oxygen ring is easily ring-opened and can be ...
Esters b. Alcohols c. Alkalines d. Ketone Which of the following statements are true of the structure of organic molecules? (Select all correct statements) A. Fatty acids are subunits of phospholipids. B. Amino acids are the subunits...
(b) What accounts for the different properties of organic and inorganic compounds? Which elements are normally present in organic compounds? Define what is organic compounds? Which of the following compounds are primary alcohols? Which of the following compounds is an organic compound? Which of the...
It is related to the hydroxy functional group (C–O–H) found in all alcohols. Silanols are often invoked as intermediates in organosilicon chemistry and silicate mineralogy. Are silicon supplements safe? Based on different studies conducted in animals and in humans, the Panel concluded that the...
Thiol, also calledmercaptan, any of a class of organic chemical compounds similar to the alcohols and phenols but containing a sulfur atom in place of the oxygen atom. What are mercaptans how are they prepared? Thiols are usually prepared by using the hydrosulfide anion (-SH) as aneucleophil...
alcoholsTHE possibility that organic compounds exist in or on interstellar grains has received much attention recently. It has been suggested that grains consist of polysaccharides 1 , carbonaceous compounds 2 or aggregates of a variety of organic compounds 3 . While it is easy to visualise how ...
