  2. 3-Methylhexane - Wikipedia

    en.wikipedia.org/wiki/3-Methylhexane

    3-Methylhexane is a branched hydrocarbon with two enantiomers. [2] It is one of the isomers of heptane . The molecule is chiral , and is one of the two isomers of heptane to have this property, the other being its structural isomer 2,3-dimethylpentane .

  3. Non-canonical base pairing - Wikipedia

    en.wikipedia.org/wiki/Non-canonical_base_pairing

    Most often the non-canonical base pairs are involved in those tertiary contacts or extra-stem base pairs. For example, some of the non-canonical base pairs in tRNA appear between the D-stem and TψC loops (Figure 5), which are close in the three-dimensional structure. Such base pairing interactions give stability to the L-shaped structure of tRNA.

  4. Transition metal hydroxide complexes - Wikipedia

    en.wikipedia.org/wiki/Transition_metal_hydroxide...

    Prominent reactions of metal hydroxides are their acid-base behavior. Protonation of metal hydroxides gives aquo complexes: L n M−OH + H + ⇌ L n M−OH + 2 where L n is the ligand complement on the metal M. Thus, aquo ligand is a weak acid, of comparable strength to acetic acid (pK a of about 4.8). [6]

  5. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    [3] Other molecules have a tetrahedral arrangement of electron pairs around a central atom; for example ammonia (NH 3) with the nitrogen atom surrounded by three hydrogens and one lone pair. However the usual classification considers only the bonded atoms and not the lone pair, so that ammonia is actually considered as pyramidal. The H–N–H ...

  6. Base pair - Wikipedia

    en.wikipedia.org/wiki/Base_pair

    An unnatural base pair (UBP) is a designed subunit (or nucleobase) of DNA which is created in a laboratory and does not occur in nature. DNA sequences have been described which use newly created nucleobases to form a third base pair, in addition to the two base pairs found in nature, A-T (adenine – thymine) and G-C (guanine – cytosine).

    The U.S. suspects Abedini was involved in a drone attack on a U.S. military base in Jordan nearly a year ago that killed three soldiers and wounded dozens. The U.S. has accused Iran of involvement ...

  9. Octahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Octahedral_molecular_geometry

    [3] One isomer in which all three pairs of identical ligands are trans; Three isomers in which one pair of identical ligands (L a or L b or L c) is trans while the other two pairs of ligands are mutually cis. Two enantiomeric pair in which all three pairs of identical ligands are cis. These are equivalent to the Δ vs Λ isomers mentioned above.
