Why is the electron geometry of a water tetrahedral while molecular geometry is V shaped?
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.
Why is the bond angle in carbon 180?
The bond angle in carbon is typically 180 degrees in a linear molecular geometry, such as in carbon dioxide (CO2), where the central carbon atom is bonded to two oxygen atoms. This angle results from the arrangement of electron pairs around the carbon atom, which minimizes electron repulsion according to VSEPR (Valence Shell Electron Pair Repulsion) theory. In this case, the two double bonds with the oxygen atoms are arranged opposite each other, leading to a linear shape. However, in other carbon compounds, such as methane (CH4) or ethene (C2H4), the bond angles differ due to varying hybridization and molecular geometry.
Does CO2 have linear geometry?
Yes it appears as O=C=O this is a result of C having 4 covalent bonds and Oxygen having 2
What is the molecular geometry if you have 3 single bonds and 1 lone pair around the central atom?
Trigonal Pyramidal
What is the difference between the arrangement of electron pairs and the shape of the molecules?
The shape of a molecule only describes the arrangement of bonds around a central atom. The arrangement of electron pairs describes how both the bonding and nonbonding electron pair are arranged. For example, in its molecular shape, a water molecule is describes as bent, with two hydrogen atoms bonded to an oxygen atom. However, the arrangement of electron pairs around the oxygen atom is tetrahedral as there are two bonding pairs (shared with the hydrogen) and also two nonbonding pairs.
What is the electron geometry of OF2?
Electron geometry for this is tetrahedral. There are two O-F single bonds, which makes 2 electron groups. There are two lone pairs around oxygen, which make up the last two electron groups. Molecules with four electron groups has a tetrahedral Electron geometry.
How would you describe the electron geometry around oxygen in water?
The electron geometry around oxygen in water is tetrahedral. This is because oxygen in water has two lone pairs of electrons and forms two sigma bonds with the two hydrogen atoms, resulting in a tetrahedral arrangement of electron pairs around the oxygen atom.
Describe the role of each of the following in predicting molecular geometries a unshared electron pairs by double bonds?
In predicting molecular geometries, unshared electron pairs and double bonds influence the overall shape of a molecule. Unshared electron pairs tend to repel bonding pairs, causing distortions in the molecular geometry. Double bonds restrict rotation around the bond axis, affecting the spatial arrangement of the surrounding atoms and leading to a fixed geometry for the molecule.
What is the hybridization about the central atom in H3O?
The central oxygen atom in H3O+ has sp3 hybridization. This means that the oxygen atom in H3O+ forms four equivalent bonds with the three hydrogen atoms and the lone pair, resulting in a tetrahedral geometry.
What is the electron domain of CH2O?
The electron domain of CH2O is three. This is because there are three regions around the central carbon atom where electrons are found: one from the double bond to oxygen and two from the carbon-hydrogen single bonds.
What is the molecular geometry for CH3I?
Since there is 4 electron domains which are all single bonds without any lone pairs, the molecular geometry is tetrahedral.
How does the VSEPR theory account for the electron pairs in double and triple bonds when determining molecular geometry?
The VSEPR theory considers electron pairs in double and triple bonds as a single entity when determining molecular geometry. This means that each double or triple bond is treated as one region of electron density, affecting the overall shape of the molecule.
What is the electron pair geometry of CS2?
This is a linear molecule just like CO2 , S=C=S around central carbon atoms there are four electrons pairs , two involved in sigma bonds and two in pi bonds , pi electrons pairs are not effective for structure determination so there are two active sets of electrons around carbon atom which are arranged at maximum possible angle 1800 , so it is a linear molecule.
Describe the Lewis dot structure for water's electron pair geometry?
The Lewis dot structure for water (H2O) shows that the oxygen atom has two lone pairs of electrons surrounding it and forms two bonds with hydrogen atoms. Its electron pair geometry is tetrahedral, with approximately 104.5 degrees bond angles due to the repulsion between lone pairs and bonded pairs.
What is the geometry the compound for dsp3 hybridization?
The geometry for a compound with dsp3 hybridization is called trigonal bipyramidal. It consists of five electron pairs arranged in a trigonal bipyramidal shape, with three equatorial bonds and two axial bonds.

What is the electronic geometry for CS2?
The electron-pair geometry of CS2 is linear because the Lewis structure is S=C=S. Double bonds act as one electron pair to help determine electron-pair geometries of molecules according to VESPR theory
