The molecular geometry of HClO is bent.
The molecular geometry of N2O2 is linear.
The molecular geometry of NHF2 is trigonal pyramidal.
Electron Pair Geometry: Tetrahedral Molecular Geometry: Bent
The molecular geometry of NBr3 is trigonal pyramidal. This is because there are three bonding pairs and one lone pair of electrons around the central nitrogen atom, causing the molecule to adopt a trigonal pyramidal shape.
Check the link, it is a sheet describing the different types of electron and molecular geometry. It helped me a lot. ^^ electron pair geometry and molecular geometry won't be the same if there are lone pairs involved.
The molecular geometry of a molecule can be determined using the VSEPR theory. VSEPR (Valence Shell Electron Pair Repulsion) Theory: The basic premise of this simple theory is that electron pairs (bonding and nonbonding) repel one another; so the electron pairs will adopt a geometry about an atom that minimizes these repulsions. Use the method below to determine the molecular geometry about an atom. Write the Lewis dot structure for the molecule. Count the number of things (atoms, groups of atoms, and lone pairs of electrons) that are directly attached to the central atom (the atom of interest) to determine the overall (electronic) geometry of the molecule. Now ignore the lone pairs of electrons to get the molecular geometry of the molecule. The molecular geometry describes the arrangement of the atoms only and not the lone pairs of electrons. If there are no lone pairs in the molecule, then the overall geometry and the molecular geometry are the same. If the overall geometry is tetrahedral, then there are three possibilities for the molecular geometry; if it is trigonal planar, there are two possibilities; and if it is linear, the molecular geometry must also be linear. The diagram below illustrates the relationship between overall (electronic) and molecular geometries. To view the geometry in greater detail, simply click on that geometry in the graphic below. Although there are many, many different geometries that molecules adopt, we are only concerned with the five shown below.
PH3 has 3 bonding pairs and 1 non-bonding pair of electrons. Its electron pair geometry is Tetrahedral and its molecular geometry is Trigonal Pyramidal.
Methane has a tetrahedral molecular geometry. It has 4 bonding pairs of electrons and no lone pairs.

The molecular geometry of secl2 is BENT.
The molecular geometry of HClO is bent.
The molecular geometry of N2O2 is linear.
The lone pair repels the electrons of the adjacent bonds more so than does a bonding pair of electrons, so thus alters the molecular geometry of the molecule.
