  3. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    In metal carbon dioxide complexes, CO 2 serves as a ligand, which can facilitate the conversion of CO 2 to other chemicals. [25] The reduction of CO 2 to CO is ordinarily a difficult and slow reaction: CO 2 + 2 e − + 2 H + → CO + H 2 O. The redox potential for this reaction near pH 7 is about −0.53 V versus the standard hydrogen electrode.

  4. Alcohol (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Alcohol_(chemistry)

    The red and white balls represent the hydroxyl group (−OH). The three "R"s stand for carbon substituents or hydrogen atoms. [1] In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom.

  7. Carbon group - Wikipedia

    en.wikipedia.org/wiki/Carbon_group

    The boiling points of the carbon group tend to get lower with the heavier elements. At standard pressure, carbon, the lightest carbon group element, sublimes at 3825 °C. Silicon's boiling point is 3265 °C, germanium's is 2833 °C, tin's is 2602 °C, and lead's is 1749 °C. Flerovium is predicted to boil at −60 °C.

  8. Ethanol - Wikipedia

    en.wikipedia.org/wiki/Ethanol

    Ethanol is a 2-carbon alcohol. Its molecular formula is CH 3 CH 2 OH. The structure of the molecule of ethanol is CH 3 −CH 2 −OH (an ethyl group linked to a hydroxyl group), which indicates that the carbon of a methyl group (CH 3 −) is attached to the carbon of a methylene group (−CH 2 –), which is

  9. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Carbon dioxide has two polar C-O bonds in a linear geometry. Carbon dioxide (CO 2 ) has two polar C=O bonds, but the geometry of CO 2 is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.
