What is the shape of ascl5?
The shape of arsenic pentachloride (AsCl5) is trigonal bipyramidal. In this molecular geometry, the arsenic atom is at the center, with five chlorine atoms positioned around it: three in a plane at 120-degree angles and two above and below this plane at 90-degree angles. This arrangement minimizes electron pair repulsion according to VSEPR theory.
Why does POCl3 does not fit the VSEPR notation?
POCl3 (phosphoryl chloride) does not fit the VSEPR notation primarily because it has a phosphorus atom that is bonded to one oxygen atom and three chlorine atoms, leading to a trigonal pyramidal molecular geometry rather than a simple arrangement. The presence of a lone pair on phosphorus contributes to the asymmetry and repulsion that alters the expected geometry. Additionally, the VSEPR model may not adequately account for the differences in electronegativity and steric effects of the different substituents in this molecule.
Is AlCl3 a trigonal planar?
It depends on the phase and the temperature Solid AlCl3 has each aluminium is 6 coordinate, surrounded by 6 chlorine atoms in an octahedral formation. The best description here is a ionic bonding. Interestingly just below melt temperature the conductivity rises indicating free ions. AlCl3 in the melt is found as dimer Al2Cl6 with four coordinate aluminium. Two chlorines bridging the aluminium atoms. In this aluminium achieves its octet and the bond angles are in line with VSEPR theory. At high temperature the dimers dissociate to monomeric AlCl3 which is trigonal planar, following VSEPR theory.
What is the bond angle and the molecular geometry of NO3?
120o. The polyatomic ion is planar with a trigonal molecular geometry, a nitrogen atom with 3 equidistant O atoms at near 122 pm. All predictable ny VSEPR. The short bond length is attributed to pi bonding, the negative charge is spread across the three O atoms.
What VSEPR formulas would predict a trigonal bipyramidal shape?
The VSEPR formulas that predict a trigonal bipyramidal shape are AX₅ and AX₄E. In both cases, there are five electron groups around the central atom, leading to a trigonal bipyramidal geometry with angles of 90° and 120°.

VSEPR formulas would predict a trigonal planar shape?
AX3
Which of these compounds would have a VSEPR formula of AXËÄ a.PF3 B.CCl4 C. BF3 D. FCl3?
D. FCl3 has a VSEPR formula of AXËÄ. This notation indicates the molecular geometry and electron pair arrangement around the central atom. In this case, FCl3 has a trigonal bipyramidal shape with 3 bonding pairs and 2 lone pairs around the central atom.
How can one determine the shape of a molecule using VSEPR theory?
To determine the shape of a molecule using VSEPR theory, one must first identify the central atom and the surrounding atoms. Then, based on the number of bonding pairs and lone pairs around the central atom, one can predict the molecular geometry using the VSEPR theory. The theory states that electron pairs repel each other and will arrange themselves in a way that minimizes repulsion, resulting in specific molecular shapes such as linear, trigonal planar, tetrahedral, trigonal bipyramidal, or octahedral.
What is the polarity of SbCl5?
The polarity of SbCl5 is nonpolar. This is because the molecule has a symmetrical trigonal bipyramidal geometry, where the chlorine atoms are arranged symmetrically around the antimony atom, resulting in no overall dipole moment.
What is the molecular shape of SCl3F as predicted by the VSEPR theory?
I believe it would be a T-shaped molecule because it has 3 bonding pairs and 2 lone pairs.
VSEPR formulas would predict a tetrahedral shape?
The VSEPR (Valence Shell Electron Pair Repulsion) theory predicts the geometric shape of a molecule based on the repulsion between electron pairs surrounding the central atom. In a molecule with four electron pairs around the central atom, the VSEPR formula would predict a tetrahedral shape, where the bond angles are approximately 109.5 degrees.
Vsepr theory to predict molecular geometry of h3o hydronium ion co3 2- sf6?
it shows tetrahedral geometry for the electron pairs geometry and trigonal pyramid the molecular geometry.
What shape is possible for the formula ab3 according to vsepr theory?
The formula ab3 corresponds to a trigonal planar shape in VSEPR theory. This means that the central atom is surrounded by three bonded atoms and has a bond angle of 120 degrees between them.
How do grups of electrons arrange themselves around the central atom according to VSEPR theory?
In VSEPR theory, electron groups (bonding pairs and lone pairs) around a central atom arrange themselves in a way that minimizes repulsion, resulting in various molecular geometries such as linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. The number of electron groups around the central atom determines the molecular geometry.
