    en.wikipedia.org/.../Dynamic_combinatorial_chemistry

    The terminology used in the field of Dynamic Combinatorial Chemistry (DCC) and Constitutional Dynamic Chemistry (CDC). [1] [2]Dynamic combinatorial chemistry (DCC); also known as constitutional dynamic chemistry (CDC) is a method to the generation of new molecules formed by reversible reaction of simple building blocks under thermodynamic control.

  3. Dioxolane - Wikipedia

    en.wikipedia.org/wiki/Dioxolane

    Dioxolane is a heterocyclic acetal with the chemical formula (CH 2) 2 O 2 CH 2. It is related to tetrahydrofuran (THF) by replacement of the methylene group (CH 2) at the 2-position with an oxygen atom. The corresponding saturated 6-membered C 4 O 2 rings are called dioxanes.

    en.wikipedia.org/wiki/Bent_molecular_geometry

    Water (H 2 O) is an example of a bent molecule, as well as its analogues. The bond angle between the two hydrogen atoms is approximately 104.45°. [ 1 ] Nonlinear geometry is commonly observed for other triatomic molecules and ions containing only main group elements, prominent examples being nitrogen dioxide (NO 2 ), sulfur dichloride (SCl 2 ...

    The equilibrium in water solution may be shifted towards either compound. For example, the equilibrium constant for the conversion of acetone (H 3 C) 2 C =O to propane-2,2-diol (H 3 C) 2 C(OH) 2 is about 10 −3, [1] while that of formaldehyde H 2 C =O to methanediol H 2 C(OH) 2 is 10 3. [2] For conversion of hexafluoroacetone (F 3 C) 2 C =O to ...

  6. Dihydrolevoglucosenone - Wikipedia

    en.wikipedia.org/wiki/Dihydrolevoglucosenone

    Dihydrolevoglucosenone can be used as a renewable building block to produce valuable chemicals such as drugs, flavours and fragrances and specialty polymers. [8]As dihydrolevoglucosenone is produced as a single enantiomer, it can be used for chiral pool synthesis.

  7. Oxygen difluoride - Wikipedia

    en.wikipedia.org/wiki/Oxygen_difluoride

    Oxygen difluoride is a chemical compound with the formula OF 2. As predicted by VSEPR theory, the molecule adopts a bent molecular geometry. [citation needed] It is a strong oxidizer and has attracted attention in rocketry for this reason. [5] With a boiling point of −144.75 °C, OF 2 is the most volatile (isolable) triatomic compound. [6]

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
