  2. VSEPR theory - Wikipedia

    en.wikipedia.org/wiki/VSEPR_theory

    In effect, they considered nitrogen dioxide as an AX 2 E 0.5 molecule, with a geometry intermediate between NO + 2 and NO − 2. Similarly, chlorine dioxide (ClO 2) is an AX 2 E 1.5 molecule, with a geometry intermediate between ClO + 2 and ClO − 2. [citation needed] Finally, the methyl radical (CH 3) is predicted to be trigonal pyramidal ...

  3. Cyclopropene - Wikipedia

    en.wikipedia.org/wiki/Cyclopropene

    The molecule has a triangular structure. The reduced length of the double bond compared to a single bond causes the angle opposite the double bond to narrow to about 51° from the 60° angle found in cyclopropane. [3]

  4. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    [11] [12] The result of VSEPR theory is being able to predict bond angles with accuracy. According to VSEPR theory, the geometry of a molecule can be predicted by counting how many electron pairs and atoms are connected to a central atom. [11] [12] Bent's rule states "[A]tomic s character concentrates in orbitals directed toward electropositive ...

  5. Trigonal pyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_pyramidal...

    This would result in the geometry of a regular tetrahedron with each bond angle equal to arccos(− ⁠ 1 / 3 ⁠) ≈ 109.5°. However, the three hydrogen atoms are repelled by the electron lone pair in a way that the geometry is distorted to a trigonal pyramid (regular 3-sided pyramid) with bond angles of 107°.

  6. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom. Molecular geometry influences several properties of a substance ...

  7. C3H4 - Wikipedia

    en.wikipedia.org/wiki/C3H4

    The molecular formula C 3 H 4 (molar mass: 40.06 g/mol, exact mass: 40.0313 u) may refer to: Cyclopropene , a cyclic alkene Propyne (a.k.a. methylacetylene), a common alkyne

  8. Rice water can be easily made at home. After you wash rice, reserve the water. "There's no other trick to it," Khetarpal explains. "You could either soak the water in the rice for like 30 minutes ...

  9. Orbital hybridisation - Wikipedia

    en.wikipedia.org/wiki/Orbital_hybridisation

    In ethene, the two carbon atoms form a σ bond by overlapping one sp 2 orbital from each carbon atom. The π bond between the carbon atoms perpendicular to the molecular plane is formed by 2p–2p overlap. Each carbon atom forms covalent C–H bonds with two hydrogens by s–sp 2 overlap, all with 120° bond angles. The hydrogen–carbon bonds ...
