  2. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− ⁠ 1 / 3 ⁠) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.

  3. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry is the three-dimensional arrangement of the atoms that ... For example, methane (CH 4) is a tetrahedral molecule. Octahedral: Octa-signifies ...

  4. Tetrahedron - Wikipedia

    en.wikipedia.org/wiki/Tetrahedron

    The tetrahedron shape is seen in nature in covalently bonded molecules. All sp 3-hybridized atoms are surrounded by atoms (or lone electron pairs) at the four corners of a tetrahedron. For instance in a methane molecule (CH 4) or an ammonium ion (NH + 4), four hydrogen atoms surround a central carbon or nitrogen atom with tetrahedral symmetry.

  5. Methane - Wikipedia

    en.wikipedia.org/wiki/Methane

    Covalently bonded hydrogen and carbon in a molecule of methane.. Methane is a tetrahedral molecule with four equivalent C–H bonds.Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H.

  6. Tetrahedrane - Wikipedia

    en.wikipedia.org/wiki/Tetrahedrane

    Tetrahedrane is a hypothetical platonic hydrocarbon with chemical formula C 4 H 4 and a tetrahedral structure. The molecule would be subject to considerable angle strain and has not been synthesized as of 2023. However, a number of derivatives have been prepared.

  7. Chloroform - Wikipedia

    en.wikipedia.org/wiki/Chloroform

    The molecule adopts a tetrahedral molecular geometry with C 3v symmetry. [14] The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom.

  8. Allotropes of phosphorus - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_phosphorus

    White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction. [2]

  9. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    The steric number of a central atom in a molecule is the number of atoms bonded to that central atom, called its coordination number, plus the number of lone pairs of valence electrons on the central atom. [11] In the molecule SF 4, for example, the central sulfur atom has four ligands; the coordination number of sulfur is four. In addition to ...
