  2. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bonded to the rest of the molecule by a single covalent bond (−CH 3), it can be found on its own in any of three forms: methanide anion (CH − 3), methylium cation (CH + 3) or methyl radical (CH • 3).

  3. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also known as the H-bond.

  4. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R) of the molecule. The acetyl moiety is a component of many organic compounds , including acetic acid , the neurotransmitter acetylcholine , acetyl-CoA , acetylcysteine , acetaminophen (also known as ...

  5. Dimethyl sulfoxide - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_sulfoxide

    Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O.This colorless liquid is the sulfoxide most widely used commercially. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.

  6. Acetonitrile - Wikipedia

    en.wikipedia.org/wiki/Acetonitrile

    Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower.

  7. Dimethyl ether - Wikipedia

    en.wikipedia.org/wiki/Dimethyl_ether

    Dimethyl ether (DME; also known as methoxymethane) is the organic compound with the formula CH 3 OCH 3, (sometimes ambiguously simplified to C 2 H 6 O as it is an isomer of ethanol).

  8. Trimethylphosphine - Wikipedia

    en.wikipedia.org/wiki/Trimethylphosphine

    It is a pyramidal molecule with approximate C 3v symmetry.The C–P–C bond angles are approximately 98.6°. [2]The C–P–C bond angles are consistent with the notion that phosphorus predominantly uses the 3p orbitals for forming bonds and that there is little sp hybridization of the phosphorus atom.

  9. Ketone - Wikipedia

    en.wikipedia.org/wiki/Ketone

    The carbonyl group is polar because the electronegativity of the oxygen is greater than that for carbon. Thus, ketones are nucleophilic at oxygen and electrophilic at carbon. Because the carbonyl group interacts with water by hydrogen bonding , ketones are typically more soluble in water than the related methylene compounds.
