AX3
The shape around S is trigonal pyramidal. Direction of deviation is less than ideal. The shape around O-H is bent (V-shaped). Direction of deviation less than ideal.
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.
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.
VSEPR theory
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°.

AX3
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.
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.
The molecular shape of SCl3F is trigonal bipyramidal, as predicted by the VSEPR theory.
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.

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.
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.
BF3 has a trigonal planar molecular geometry according to the VSEPR theory. It consists of three bonding pairs around the central Boron atom, resulting in a flat, trigonal planar shape.
