  2. 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

  3. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    Different ways of representing a methyl group (highlighted in blue). In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4).

  4. Acetyl group - Wikipedia

    en.wikipedia.org/wiki/Acetyl_group

    In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3.It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium).

  5. 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).

  6. Methine group - Wikipedia

    en.wikipedia.org/wiki/Methine_group

    Methine or methylylidene (IUPAC) In organic chemistry, a methine group or methine bridge is a trivalent functional group =CH−, derived formally from methane.It consists of a carbon atom bound by two single bonds and one double bond, where one of the single bonds is to a hydrogen.

  7. Acetyl cyanide - Wikipedia

    en.wikipedia.org/wiki/Acetyl_cyanide

    Two main types of reactions can occur with acetyl cyanide as a reactant; aldol condensation and enolate substitution. Aldol condensation can occur when acetyl cyanide reacts with (Z)-but-2-enal to form (2E,4E)-hexa-2,4-dienoyl cyanide:

  8. Carbon–hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–hydrogen_bond

    Because of this small difference in electronegativities, the C−H bond is generally regarded as being non-polar. In structural formulas of molecules, the hydrogen atoms are often omitted. Compound classes consisting solely of C−H bonds and C−C bonds are alkanes, alkenes, alkynes, and aromatic hydrocarbons.

  9. Trimethylamine - Wikipedia

    en.wikipedia.org/wiki/Trimethylamine

    Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3.It is a trimethylated derivative of ammonia.TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7]
