3-Methylhexane is a branched hydrocarbon with two enantiomers. [2] It is one of the isomers of heptane . The molecule is chiral , and is one of the two isomers of heptane to have this property, the other being its structural isomer 2,3-dimethylpentane .
Methyl hexanoate is the fatty acid methyl ester of hexanoic acid (caproic acid), a colourless liquid organic compound with the chemical formula CH 3 −(CH 2) 4 −COO−CH 3. It is found naturally in many foods and has a role as a plant metabolite. It can also be found in the cytoplasm of cells. [1]
The ECW model is a quantitative model that describes and predicts the strength of Lewis acid base interactions, −ΔH. The model assigned E and C parameters to many Lewis acids and bases. Each acid is characterized by an E A and a C A. Each base is likewise characterized by its own E B and C B. The E and C parameters refer, respectively, to ...
The intrinsic DNA fluorescence was discovered in the 1960s by studying nucleic acids in frozen media. [1] Since the beginning of the 21 st century, the much weaker emission of nucleic acids in fluid solutions is being studied in room temperature by means sophisticated spectroscopic techniques using as UV source femtosecond laser pulses and ...
In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.
A similar process can also be used to prevent self-condensation between two ketones. In this case, however, the base used needs to be more powerful. A common base used is Lithium diisopropyl amide (LDA). Here it is used in order to perform the crossed condensation between acetone and cyclohexanone. [3]
A simple buffer solution consists of a solution of an acid and a salt of the conjugate base of the acid. For example, the acid may be acetic acid and the salt may be sodium acetate . The Henderson–Hasselbalch equation relates the pH of a solution containing a mixture of the two components to the acid dissociation constant , K a of the acid ...
Isovaleric acid, also known as 3-methylbutanoic acid or β-methylbutyric acid, is a branched-chain alkyl carboxylic acid with the chemical formula (CH 3) 2 CHCH 2 CO 2 H. It is classified as a short-chain fatty acid. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. The compound occurs naturally and can be found in ...
