You drew the Lewis structures of the following compounds and ion in Assessment 2.32. Predict their shapes around the central atom based on the Lewis structure.
(c) HCO2H
Guida verificata passo dopo passo1
Draw the Lewis structure of HCO₂H (formic acid). Identify the central atom, which is the carbon atom, and ensure all valence electrons are accounted for. Carbon will form a double bond with one oxygen atom, a single bond with the other oxygen atom (which is also bonded to a hydrogen atom), and a single bond with the hydrogen atom.
Determine the regions of electron density around the central carbon atom. In this case, there are three regions of electron density: one double bond to oxygen, one single bond to oxygen, and one single bond to hydrogen.
Apply the VSEPR (Valence Shell Electron Pair Repulsion) theory. According to VSEPR, the regions of electron density will arrange themselves as far apart as possible to minimize repulsion. For three regions of electron density, the geometry is trigonal planar.
Predict the molecular shape around the central carbon atom. Since there are no lone pairs on the central carbon atom, the molecular shape will also be trigonal planar.
Verify the bond angles. In a trigonal planar geometry, the bond angles are approximately 120°. Confirm that this matches the expected geometry for HCO₂H.

Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Lewis Structures
Lewis structures are diagrams that represent the bonding between atoms in a molecule and the lone pairs of electrons that may exist. They help visualize the arrangement of electrons and the connectivity of atoms, which is crucial for predicting molecular geometry. In the case of HCO₂H (formic acid), drawing the Lewis structure allows us to identify the central atom and its bonding partners.
VSEPR Theory
Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom. According to VSEPR, electron pairs will arrange themselves to minimize repulsion, leading to specific molecular shapes. For HCO₂H, understanding VSEPR helps determine the shape around the central carbon atom.
Molecular Geometry
Molecular geometry refers to the three-dimensional arrangement of atoms in a molecule. It is influenced by the number of bonding pairs and lone pairs of electrons around the central atom. In HCO₂H, the molecular geometry can be predicted by analyzing the Lewis structure and applying VSEPR theory, which indicates that the shape will be influenced by the presence of both single and double bonds.

Calculate the formal charge on the non-hydrogen atoms in the molecules shown. Use the arrow-pushing formalism to 'move' an electron pair such that it is shared between two (formerly) charged atoms. Your arrow should account for the formation of the molecule on the right from the molecule on the left.
