Formally, a carbanion is the conjugate base of a carbon acid: R 3 CH + B − → R 3 C − + HB. where B stands for the base. The carbanions formed from deprotonation of alkanes (at an sp 3 carbon), alkenes (at an sp 2 carbon), arenes (at an sp 2 carbon), and alkynes (at an sp carbon) are known as alkyl, alkenyl , aryl, and alkynyl anions ...
As a rule, however, these neutral oxocarbons are less stable than the corresponding anions. Thus, for example, the stable carbonate anion corresponds to the extremely unstable neutral carbon trioxide CO 3; [2] oxalate C 2 O 2− 4 correspond to the even less stable 1,2-dioxetanedione C 2 O 4; [3] and the stable croconate anion C 5 O 2−
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −). Sodium bicarbonate is a white solid that is crystalline but often appears as a
The S N 2 reaction between sodium acetate and bromoethane. The products are ethyl acetate and sodium bromide. The nucleophilicity of carboxylate ions is much weaker than that of hydroxide and alkoxide ions, but stronger than that of halide anions (in a polar aprotic solvent, though there are other effects such as solubility of the ion).
The most important sodium compounds are table salt (NaCl), soda ash (Na 2 CO 3), baking soda (NaHCO 3), caustic soda (NaOH), sodium nitrate (NaNO 3), di- and tri-sodium phosphates, sodium thiosulfate (Na 2 S 2 O 3 ·5H 2 O), and borax (Na 2 B 4 O 7 ·10H 2 O). [24] In compounds, sodium is usually ionically bonded to water and anions and is ...
The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.
Carbon trioxide (CO 3) is an unstable oxide of carbon (an oxocarbon). The possible isomers of carbon trioxide include ones with molecular symmetry point groups C s , D 3h , and C 2v . The C 2v state, consisting of a dioxirane , has been shown to be the ground state of the molecule. [ 1 ]
