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
A^6
trigonal bipyramidal, there are 5 e- by VSEPR method
AX3
trigonal planar
it shows tetrahedral geometry for the electron pairs geometry and trigonal pyramid the molecular geometry.
IF7 is pentagonal bipyramidal
It would be trigonal planar, with bond angles of 120º.
VSEPR predict the geometry of a chemical molecule.
It has a linear shape
SbCl5 is non-polar because it has a Trigonal Bipyramid VSEPR shape
BH3 has a trigonal planar shape with 120 angles.
