1: Both the lone pairs asa well as the bond pairs participate in determining the geometery of the molecules 2: The electron pairs are arranged around the central polyvalent atom so as to remain at a miximum distance apart to avoid repulsions 3: The electron pairs of lone pairs occupy more space then the bond pairs
from ncert:-
1)The shape of a molecule depends upon
the number of valence shell electron pairs
(bonded or nonbonded) around the central
atom.
2)Pairs of electrons in the valence shell repel
one another since their electron clouds are
negatively charged.
3)These pairs of electrons tend to occupy
such positions in space that minimise
repulsion and thus maximise distance
between them.
3)The valence shell is taken as a sphere with
the electron pairs localising on the
spherical surface at maximum distance
from one another.
4)A multiple bond is treated as if it is a single
electron pair and the two or three electron
pairs of a multiple bond are treated as a
single super pair.

Where two or more resonance structures
can represent a molecule, the VSEPR
model is applicable
the VSEPR theory
Electron pairs
VSEPR theory is important because it helps predict the molecular geometry of molecules based on the number of bonding and nonbonding pairs of electrons around the central atom. This is crucial in understanding the shape of molecules, which is fundamental in determining their physical and chemical properties. Additionally, VSEPR theory aids in explaining molecular polarity and reactivity.
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.
VSEPR is "Valence shell electron pair repulsion".
The molecular geometry of CHCl3, according to VSEPR theory, is tetrahedral.
The molecular geometry of SO2 according to the VSEPR theory is bent.
the VSEPR theory
According the VSEPR theory of molecular geometry, the geometry of SCl2 would be the same as H2O which is a bent angle
what is the theory of delton
Electron pairs
VSEPR theory helps predict the molecular geometry of a molecule based on the arrangement of its electron pairs. Hybridization explains how atomic orbitals mix to form new hybrid orbitals, which influences the molecular shape predicted by VSEPR theory. In essence, hybridization determines the geometry of a molecule based on the VSEPR theory.
no, not all molecules obey the VSEPR theory, there is an exeption considered for the SIO2 molecules which obeys not the VSEPR theory
The molecular geometry of a molecule with the keyword "bro3" according to the VSEPR theory is trigonal pyramidal.

The correct answer is: Why molecules have different shapes.
