Are electron pair geometry and molecular geometry the same?
The molecular geometry definition in chemistry is the arrangement of atoms in relation to a central atom in three-dimensional space. Electron geometry is the arrangement of electron groups. If all the electron groups are bonded, with no lone pairs, then the electron geometry and molecular geometry are the same.
What is the electron geometry of bcl2?
BCl2 is nonlinear with a ClBCl angle of approximately 122° and with the unpaired electron mainly localized on the boron atom.
Is CH3CHO a linear molecule?
The molecule is linear in geometry and shape because there are two electron groups surrounding each central C atom.
Why is CH3CHO polar?
Here in the structure of the acetaldehyde there is presence of unbounded electrons on O-atom. This means there is uneven distribution of electrons. So that the right end of the acetaldehyde shows more negative than its right end. Thus, due to this uneven distribution of electrons, it acts as polar molecule.
Under what circumstances are electron geometry and molecular geometry not the same?
Under what circumstances are they not the same? -Electron geometry is the arrangement of the electron groups. -Molecular geometry is the geometrical arrangements of the atoms. -When a molecule contains one or more lone pairs, then the molecular geometry differs from the electron geometry.
Which is more accurate molecular geometry or electron pair geometry?
Which is more accurate: Molecular Geometry or Electron Pair Geometry (as predicted by VSEPR)? Electron pair geometry is more accurate because lone pairs and bonding pairs are identical b.)
What is the molecular geometry of a molecule with 4 outer atoms and 1 lone pair on the central atom?
| # of bonding groups/domains on ‘central’ atom | # of lone pair electrons on ‘central’ atom | Molecular Geometry |
|---|---|---|
| 4 | 0 | tetrahedral |
| 3 | 1 | trigonal pyramidal |
| 2 | 2 | bent |
| 5 | 0 | trigonal bipyramidal |
What is the electron-pair geometry of bh2?
The lone pair on boron will repel the two B-H bonds away from it. Thus, the shape is actually bent and not linear. Furthermore, the angles are not exactly 120 degrees as in the case of a trigonal planar molecule where the surrounding atoms are all the same.
