What geometry will you have if you have three single bonds on a central atom?
If these are all bond pairs the molecular geometry is tetrahedral (e.g. CH4). If there is one lone pair of electrons and three bond pairs the resulting molecular geometry is trigonal pyramidal (e.g. NH3).
What is the molecular geometry for a compound that has 3 single bonds around the central and 1 lone pair also around the central atom?
| # of bonding groups/domains on ‘central’ atom | # of lone pair electrons on ‘central’ atom | Molecular Geometry |
|---|---|---|
| 3 | 0 | trigonal planar |
| 2 | 1 | bent |
| 4 | 0 | tetrahedral |
| 3 | 1 | trigonal pyramidal |
What is the molecular geometry of a molecule that has 3 electron pairs on the central atom all of them are bonds?
3 we see that with three bonding pairs around the central atom, the molecular geometry of BCl3 is trigonal planar, as shown in Figure 10.2. 2.
What is the molecular geometry for a molecule with 3 atoms bonded to the central atom?
trigonal pyramidal
When a central atom is bonded to three atoms and has one lone pair of electrons, the overall shape is trigonal pyramidal.
What is the shape of the molecule when this atom makes three single bonds to three hydrogen atoms?
Explanation: But the geometry of the molecule is trigonal pyramidal, inasmuch as we describe molecular geometry on the basis of atoms AND NOT electronic geometry.
What is the molecular geometry of a molecule with 3 outer atoms and 2 lone pairs on the central atom?
Recall that the trigonal bipyramidal geometry has three equatorial atoms and two axial atoms attached to the central atom. Because of the greater repulsion of a lone pair, it is one of the equatorial atoms that are replaced by a lone pair. The geometry of the molecule is called a distorted tetrahedron, or seesaw.
What is the electron geometry if you have 3 electron groups around the center atom quizlet?
the most stable shape for three electron domains around a central atom is trigonal planar, with 120° bond angles.
What geometric arrangement of charge clouds is expected for an atom that has three charge clouds?
The answer is D) trigonal bipyramidal.
What is the molecular geometry of a molecule with 3 outer atoms?
What geometric arrangement of electron groups is expected for an atom that has three electron groups?

| 4 | tetrahedral | “pyramidal” |
What is the molecular geometry of a molecule with 3 outer atoms and 3 lone pairs on the central atom?

What is the molecular geometry of a linear molecule with three atoms?
Linear molecular geometry. The most important linear molecule with more than three atoms is acetylene (H−C≡C−H), in which each of its carbon atoms is considered to be a central atom with a single bond to one hydrogen and a triple bond to the other carbon atom. As described by the VSEPR model, the five valence electron pairs on…
How do the geometries of molecules with lone pairs differ?
The geometries of molecules with lone pairs will differ from those without lone pairs, because the lone pair looks like empty space in a molecule. Both classes of geometry are named after the shapes of the imaginary geometric figures (mostly regular solid polygons) that would be centered on the central atom and have an electron pair at each vertex.
What is the basic geometry for a molecule containing four electrons?
The basic geometry for a molecule containing a central atom with four pairs of electrons is tetrahedral. An example of this geometry is CH 4.
Why do 5-coordinated molecules with lone pairs have equatorial plane?
In 5-coordinated molecules containing lone pairs, these non-bonding orbitals (which are closer to the central atom and thus more likely to be repelled by other orbitals) will preferentially reside in the equatorial plane. This will place them at 90° angles with respect to no more than two axially-oriented bonding orbitals.
