  2. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  3. Cyclobutadiene - Wikipedia

    en.wikipedia.org/wiki/Cyclobutadiene

    Cyclobutadiene is an organic compound with the formula C 4 H 4. It is very reactive owing to its tendency to dimerize . Although the parent compound has not been isolated, some substituted derivatives are robust and a single molecule of cyclobutadiene is quite stable.

  4. Annulene - Wikipedia

    en.wikipedia.org/wiki/Annulene

    Using this form of nomenclature 1,3,5,7-cyclooctatetraene is [8]annulene and benzene is [6]annulene (and occasionally referred to as just 'annulene'). [ 2 ] [ 3 ] The discovery that [18]annulene possesses a number of key properties associated with other aromatic molecules was an important development in the understanding of aromaticity as a ...

  5. Benzocyclobutadiene - Wikipedia

    en.wikipedia.org/wiki/Benzocyclobutadiene

    Benzocyclobutadiene is the simplest polycyclic hydrocarbon, being composed of an aromatic benzene ring fused to an anti-aromatic cyclobutadiene ring. It has chemical formula C 8 H 6 . Though the benzene ring is stabilized by aromaticity , the cyclobutadiene portion has a destabilizing effect.

  6. Cyclobutene - Wikipedia

    en.wikipedia.org/wiki/Cyclobutene

    The compound was first prepared by thermolysis of the ammonium salt [C 4 H 7 N(CH 3) 3]OH (cyclobutyltrimethylammonium hydroxide). [2] Cyclobutene thermally isomerizes to 1,3-butadiene. This strongly exothermic reaction reflects the dominance of ring strain. In contrast, the corresponding equilibrium for hexafluorocyclobutene disfavors ...

  7. Bicyclobutane - Wikipedia

    en.wikipedia.org/wiki/Bicyclobutane

    Bicyclo[1.1.0]butane is an organic compound with the formula C 4 H 6. It is a bicyclic molecule consisting of two cis -fused cyclopropane rings, and is a colorless and easily condensed gas. [ 1 ] Bicyclobutane is noted for being one of the most strained compounds that is isolatable on a large scale — its strain energy is estimated at 63.9 ...

    en.wikipedia.org/wiki/Cyclobutadieneiron_tricarbonyl

    Cyclobutadieneiron tricarbonyl is an organoiron compound with the formula Fe(C 4 H 4)(CO) 3. It is a yellow oil that is soluble in organic solvents. It has been used in organic chemistry as a precursor for cyclobutadiene, which is an elusive species in the free state. [1]

  9. Diisopropylbenzene - Wikipedia

    en.wikipedia.org/wiki/Diisopropylbenzene

    The diisopropylbenzenes (DIPB) are organic compounds with the formula C 6 H 4 (CH(CH 3) 2) 2. Three isomers exist: 1,2- 1,3-, and 1,4-diisopropylbenzene. All are colorless liquids, immiscible in water, with similar boiling points. They are classified are aromatic hydrocarbons bearing a pair of isopropyl (CH(CH 3) 2) substituents. [1]
