Attachment of vinyl group or phenyl group directly to carboxylic acid group has effect on the acidic character of that carboxylic acid. Explain. View Solution Which of the sulphides of group II is orange ? View Solution Exams IIT JEE
The greater acidity of thiosilanoic acid derivatives over their thiocarboxylic acid counterparts is largely due to electrostatic interactions. The more electropositive silicon imparts more ionic character to the bonds in thiosilanoic acids compared to carboxylic acids. Computed vibrational frequencies ...
Thus, suppression of HMGA protein expression has been suggested as a potential way for therapeutic intervention of human malignant neoplasia (Scala et al., 2000). The multi-functionality of HMGA1a is achieved through its high adaptability, due to its intrinsically disordered character (Sgarra et ...
Similarly, if we look at butanoic acid, the C=O bond makes, the same carbon more electropositive, and that is why the carboxylic acid compounds are stronger acids as compared to the corresponding alcohol. The pH of butanoic acid is close to 4; thus, it is much stronger than the correspo...
Therefore, because of their superior character, such as non volatility and high stability, SO3H-functionalized ionic liquids could become the substitute of liquid inorganic acids in many cases of industrial application. On the other hand, the acidity–catalytic activity relationship was generally studied...
very general scope, that is to say the present method is appropriate for the stabilization of any acidic emulsion (having a pH below or equal to 3.5) of the oil-in-water type, already known per se or otherwise, the composition of the latter not assuming, in fact, any critical character...
Two carboxylate C-O bond lengths ranges, namely differing 1.29/1.22 Å for 2, and the same 1.24/1.24 Å for 3, respectively, are in agreement with the single (longer)/double (shorter) character of both bonds for the neutral carboxylic HL in 2, and the same character of both bonds ...

nitric acid and sulfuric acid may also be used, however are less preferred due to their strong acidic character; if present are present in only minor amounts. However, the use of water soluble acids as co-acids are preferred, including water soluble salts of organic acids. When present, the...
