McGraw-Hill purchased Schaum Publishing Company in 1967. [2] Titles are continually revised to reflect current educational standards in their fields, including updates with new information, additional examples, use of new technology (calculators and computers), and so forth. New titles are also introduced in emerging fields such as computer ...
Because DMSO accepts protons more strongly than H 2 O the acid becomes stronger in this solvent than in water. [11] Indeed, many molecules behave as acids in non-aqueous solutions but not in aqueous solutions. An extreme case occurs with carbon acids, where a proton is extracted from a C−H bond. [12] Some non-aqueous solvents can behave as acids.
In organic chemistry, methenium (also called methylium, carbenium, [2] methyl cation, or protonated methylene) is a cation with the formula CH + 3. It can be viewed as a methylene radical (: CH 2) with an added proton (H +), or as a methyl radical (• CH 3) with one electron removed.
A crystal structure for the analogous diphenylmethanide anion ([Li(12-crown-4)] + [CHPh 2] −), prepared form diphenylmethane (pK a in DMSO of CH 2 Ph 2 = 32.3), was also obtained. However, the attempted isolation of a complex of the benzyl anion PhCH − 2 from toluene (p K a in DMSO of CH 3 Ph ≈ 43) was unsuccessful, due to rapid reaction ...
The CRC Handbook of Chemistry and Physics is a comprehensive one-volume reference resource for science research. First published in 1914, it is currently (as of 2024) in its 105th edition, published in 2024. It is known colloquially among chemists as the "Rubber Bible", as CRC originally stood for "Chemical Rubber Company". [2]
The exact relationship depends on the nature of the reactions at the two electrodes. For the electrolysis of aqueous copper(II) sulfate (CuSO 4) as an example, with Cu 2+ (aq) and SO 2− 4 (aq) ions, the cathode reaction is the reduction Cu 2+ (aq) + 2 e − → Cu(s) and the anode reaction is the corresponding oxidation of Cu to Cu 2+.
Ferric acetate is the iron compound with the formula Fe 3 O(O 2 CCH 3) 6 (H 2 O) 3]O 2 CCH 3. This red brown solid is the acetate salt of the coordination complex [Fe 3 O(OAc) 6 (H 2 O) 3] + (OAc − is CH 3 CO 2 −). Commonly, the salt is known as "basic iron acetate". [2] The formation of the red-brown complex was once used as a test for ...
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
