∙ 11y agoSuch a molecule is trigonal but due to presence of lone pair the bond angle is less than 120 degree as HNO2 the central atom is nitrogen. O=N..-OH

∙ 15y agoThe molecule will have a bent shape due to the presence of two lone pairs on the central atom. The lone pairs will repel the outer atoms, causing the bond angles to be less than 120 degrees. This geometry is known as angular or bent.

∙ 14y agoIt is a tetrahedral. If it has 4 single bonds, like in this case, it is sp3 hybridized and has a molecular geometry of tetrahedral.
An example is CH4.

This is a linear molecule.
There is one central atom of oxygen (O) in an O3 molecule.
Electron geometry describes the arrangement of electron pairs around a central atom in a molecule, based on the total number of electron pairs (bonding and nonbonding). Molecular geometry, on the other hand, describes the arrangement of atoms, taking into account only the positions of the atoms. They will not be the same when there are lone pairs of electrons on the central atom. In such cases, the electron geometry is determined by all electron pairs, whereas the molecular geometry considers only the positions of the atoms, leading to a difference.
The molecular shape of CIF2 is linear. This is because there are only two atoms bonded with the central atom, which results in a linear molecular geometry.
The molecular geometry of CS2 is linear. This molecule consists of a central carbon atom bonded to two sulfur atoms, and there are no lone pairs on the central atom. The bonds and atoms are arranged in a straight line, giving it a linear molecular geometry.
The molecular geometry of this molecule is bent. Click on the related link for a Wikipedia article that contains a VSEPR table.

This is a linear molecule.
The molecular geometry characterized by 109.5 degree bond angles is tetrahedral. This geometry occurs when a central atom is bonded to four surrounding atoms with no lone pairs on the central atom. An example of a molecule with this geometry is methane (CH4).
The conclusion of molecular geometry is the three-dimensional arrangement of atoms that determines a molecule's shape. By understanding the arrangement of atoms, scientists can predict a molecule's physical and chemical properties.
The molecular geometry of HOCN is trigonal planar. This is because the molecule has a central carbon atom with three surrounding atoms (one oxygen, one hydrogen, and one nitrogen) arranged in a flat, triangular shape. This configuration leads to a trigonal planar molecular geometry.
Silicon Tetrafluoride has a tetrahedral molecular geometry. That means there are 4 F atoms around the central atom Si.
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.
Electron geometry describes the arrangement of electron pairs around a central atom in a molecule, based on the total number of electron pairs (bonding and nonbonding). Molecular geometry, on the other hand, describes the arrangement of atoms, taking into account only the positions of the atoms. They will not be the same when there are lone pairs of electrons on the central atom. In such cases, the electron geometry is determined by all electron pairs, whereas the molecular geometry considers only the positions of the atoms, leading to a difference.
The molecular geometry of chloroform (CHCl3) is tetrahedral. This means that the central carbon atom is surrounded by three hydrogen atoms and one chlorine atom, with the bond angles between these atoms being approximately 109.5 degrees.
