WebOct 4, 2024 · Some compounds have acidic C-H bonds, despite the fact that many hydrocarbons have extremely high pKa's (such as methane, CH4, pKa = 50). Explain … Webenolate anion is in equilibrium with free acetone as the pKa of acetone is 19.3 and NaOH is not a sufficiently strong enough base to ensure complete deprotonation. However, as benzaldehyde is a more reactive electrophile than acetone, the enolate will selectively act as a nucleophile towards it, forming a β-hydroxyketone intermediate. Both of ...
WebCubane (C 8 H 8) is a synthetic hydrocarbon compound that consists of eight carbon atoms arranged at the corners of a cube, with one hydrogen atom attached to each carbon atom. A solid crystalline substance, cubane is one of the Platonic hydrocarbons and a member of the prismanes.It was first synthesized in 1964 by Philip Eaton and Thomas Cole. ... WebThe stabilization of the carbanion provided by the phosphorus causes an increase in acidity (pKa ~35). Very strong bases, such as butyl lithium, are required for complete formation of ylides. The ylides shown here are all strong bases. Like other strongly basic organic reagents, they are protonated by water and alcohols, and are sensitive to ...

WebIf the formed enolate is stabilized by more than one carbonyl it is possible to use a weaker base such as sodium ethoxide. NaOCH 2 CH 3 = Na + - OCH 2 CH 3 = NaOEt. Because of the acidity of α hydrogens, carbonyls undergo keto-enol tautomerism. Tautomers are rapidly interconverted constitutional isomers, usually distinguished by a different ...
