Oxygen has 6 electrons in its outer shell but attains 8 when it bonds with the two hydrogen atoms in a water molecule. This makes 4 pairs of two. Theelectron geometry is therefore a tetrahedral (4 apices). Because the two hydrogens are attached to two of these apices they form a V shape.

A tetrahedral die (not dice!) is a triangle-based pyramid, whose four faces are equilateral triangles.
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.
According to Euclidean geometry, that is an object where all the angles are the same and all the sides are the same length.
The electron domain geometry of BrF3 is T-shaped. It consists of two bonding domains and three lone pairs of electrons around the central bromine atom, resulting in a T-shaped molecular geometry.
The molecular geometry of OF2 is bent or V-shaped. This is because it has two bonding pairs and two lone pairs around the central oxygen atom, resulting in a bent shape.
OF2 will adopt a bent or V-shaped geometry due to the presence of two lone pairs on the oxygen atom, resulting in a molecular shape that is angular.

The VSEPR (Valence Shell Electron Pair Repulsion) theory for N2H4 (hydrazine) predicts a trigonal pyramidal molecular geometry around each nitrogen atom due to the presence of two lone pairs on each nitrogen atom. This results in a bent molecular shape for N2H4.

A molecule with two bonded groups and two lone pairs will have a bent or V-shaped geometry. The apex of the molecule will be where the two bonded groups meet, causing the lone pairs to be directed away from each other. This geometry is characteristic of molecules with a steric number of four and a tetrahedral electron geometry.
Iodine trichloride (ICl3) is a T-shaped molecular structure. It consists of three chlorine atoms bonded to a central iodine atom, with bond angles of about 90 degrees.
Ammonium (NH4+) is tetrahedral shaped because it has four electron pairs around the central nitrogen atom, leading to a symmetrical arrangement with bond angles of approximately 109.5 degrees. This geometry minimizes repulsion between the electron pairs, resulting in a stable molecular structure.
The NH3 molecule has a trigonal pyramidal molecular geometry, where the nitrogen atom is at the center with three hydrogen atoms bonded to it. The lone pair on nitrogen contributes to the overall shape by pushing the hydrogen atoms closer together, resulting in a pyramid-like structure.
The electron domain geometry of NO2 is bent or V-shaped, with an angle of approximately 134 degrees. This is because NO2 has two electron domains around the nitrogen atom, resulting in a bent molecular geometry.
a) ClF4- has a square planar geometry due to its five electron domains, with four bonding pairs and one lone pair. b) ClF4+ has a linear geometry with no lone pairs, resulting in a linear molecular shape. c) NO2- has a T-shaped geometry with three electron domains - one lone pair and two bonding pairs. d) BrF3 has a bent molecular geometry due to the presence of two lone pairs and two bonding pairs around the central atom. e) CO2 has a linear molecular geometry as it has two electron domains and no lone pairs around the central carbon atom.
