Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.
Infobox references. A carbonate is a salt of carbonic acid, H2CO3, [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO2− 3. The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group O=C (−O−)2. The term is also used as a verb, to describe ...
Carbon trioxide (CO3) is an unstable oxide of carbon (an oxocarbon). The possible isomers of carbon trioxide include ones with molecular symmetry point groups Cs, D3h, and C2v. The C2v state, consisting of a dioxirane, has been shown to be the ground state of the molecule. [1] Carbon trioxide should not be confused with the stable carbonate ion ...
Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded ...
The most important resonance form of carbon monoxide is – C≡O +. An important minor resonance contributor is the non-octet carbenic structure :C=O. Carbon monoxide has a computed fractional bond order of 2.6, indicating that the "third" bond is important but constitutes somewhat less than a full bond. [20]
Carbon suboxide, or tricarbon dioxide, is an organic, oxygen -containing chemical compound with formula C3O2 and structure O=C=C=C=O. Its four cumulative double bonds make it a cumulene. It is one of the stable members of the series of linear oxocarbons O=Cn=O, which also includes carbon dioxide (CO2) and pentacarbon dioxide (C5O2).
Chemist Linus Pauling first developed the hybridisation theory in 1931 to explain the structure of simple molecules such as methane (CH 4) using atomic orbitals. [2] Pauling pointed out that a carbon atom forms four bonds by using one s and three p orbitals, so that "it might be inferred" that a carbon atom would form three bonds at right angles (using p orbitals) and a fourth weaker bond ...
Keeping this structure in mind, it makes sense that the substituent that can maintain positive charge the best would be most likely to migrate. [9] The higher the degree of substitution, the more stable a carbocation generally is. [10] Therefore, the tertiary > secondary > primary trend is observed.
