The VSEPR formula for the compound H½O is AX₂E, where A is the central atom (Oxygen), X is the number of atoms bonded to the central atom (2 hydrogens), and E is the number of lone pairs on the central atom (1 lone pair). This leads to a bent molecular geometry for water.
The Valence shell electron pair repulsion, or VSEPR is a simple technique for predicting the shape or geometry of atomic centers. The VSEPR formula is used in small molecules and molecular ions.
The shape of chloromethane is tetrahedral.
I believe it would be a T-shaped molecule because it has 3 bonding pairs and 2 lone pairs.
Br3Cl5 is least likely to represent a compound that really exists because it violates the octet rule, which states that atoms tend to combine in such a way that each atom has a full valence shell of electrons. In Br3Cl5, bromine would have more than an octet of electrons around it, which is energetically unfavorable.
The VSEPR formula for the compound SF₄ is AX₄E, where A represents the central atom (Sulfur) and E represents the lone pairs of electrons. Each "A" is surrounded by four "X" atoms (Fluorine atoms) and one "E" lone pair.
The VSEPR formula for the compound H½O is AX₂E, where A is the central atom (Oxygen), X is the number of atoms bonded to the central atom (2 hydrogens), and E is the number of lone pairs on the central atom (1 lone pair). This leads to a bent molecular geometry for water.

The Valence shell electron pair repulsion, or VSEPR is a simple technique for predicting the shape or geometry of atomic centers. The VSEPR formula is used in small molecules and molecular ions.
The VSEPR formula for a polar molecule would involve a central atom bonded to small, highly electronegative atoms like fluorine or oxygen. For example, molecules like BF3 (Trigonal Planar) or H2O (Bent) tend to have greater polarity due to the electronegativity differences between the central atom and surrounding atoms.
The VSEPR formulas that predict a trigonal bipyramidal shape are AX₅ and AX₄E. In both cases, there are five electron groups around the central atom, leading to a trigonal bipyramidal geometry with angles of 90° and 120°.
C2h4o
The VSEPR (Valence Shell Electron Pair Repulsion) theory predicts the geometric shape of a molecule based on the repulsion between electron pairs surrounding the central atom. In a molecule with four electron pairs around the central atom, the VSEPR formula would predict a tetrahedral shape, where the bond angles are approximately 109.5 degrees.
According the VSEPR theory of molecular geometry, the geometry of SCl2 would be the same as H2O which is a bent angle
The shape of chloromethane is tetrahedral.
Ax5
For the anion in the covalent compound CH3, the Greek prefix used to represent it is "meth-." So, the anion in CH3 would be called "methide."
