This is the maximum distance the atoms can be placed away from each other. If you change any of the angles, some of the atoms will be closer together and will experience steric repulsions. By placing the atoms 109.5 degrees apart, you minimize steric repulsions and free energy. ------------------------------------------------------ Edit (AY12345): You know the shape of the molecule. Draw it out. Use a little trigonometry, and the angles can be calculated mathematically.

What is the molecular geometry of CF3Cl?
It is a tetrahedral. When making a Lewis structure, you will see 4 effective bonds. Then use a VESPR chart, and you will find it is a tetrahedral.
What is the electronic geometry of methane?
All of the hydrogens on methane are evenly spaced apart at 109.5 degree bonds. This makes the geometry tetrahedral.
Molecular geometry of SO2Cl2?
Tetrahedral. It is because in this molecular the central atom S have four bonds and no lone pairs. So the shape must and must be what I said.
What is the molecular geometry for CBr4?
whenever carbon atom forms four covalent bonds the basic structure is tetrahedral because carbon in such cases is sp3 hybridized.
What is the molecular geometry of SiCl2F2?
Tetrahedral. Si can [and will naturally try to] create four bonds with its electrons to fill its valence shell. The other four atoms in this molecule have a charge of -1 each, so all four of these atoms will bond directly with Si and space themselves out to maximum distance of each other. Four electron domains = tetrahedral.
What bonds angles are found in tetrahedral compounds?
In tetrahedral compounds, the bond angles are approximately 109.5 degrees. This is due to the tetrahedral geometry, where the four bonding pairs of electrons repel each other equally, resulting in a symmetric arrangement and the optimal angle of 109.5 degrees between the bonds.
What is the molecular geometry around the carbon in CF4 is?
The molecular geometry around the carbon in CF4 is tetrahedral. The carbon atom is bonded to four fluorine atoms, with the bond angles between the C-F bonds being approximately 109.5 degrees.
What is the shape of a carbon atom as is bonds to four other atoms?
A carbon atom forms a tetrahedral shape when it bonds to four other atoms. This arrangement allows for each of the bonds to be at angles of approximately 109.5 degrees to one another, maximizing the distance between bonding electrons and minimizing repulsion.
Why is methane tetrahedral?
Methane (CH4) is tetrahedral because the carbon atom is bonded to four hydrogen atoms, creating a symmetric, three-dimensional structure with bond angles of 109.5 degrees. This arrangement allows for maximum separation between the bonding electron pairs, minimizing repulsion and stabilizing the molecule.
What is the molecular shape of CCl4?
The molecular shape of CCl4 is tetrahedral. Carbon is the central atom surrounded by four chlorine atoms, each forming a single covalent bond. This arrangement results in a symmetric tetrahedral shape.
What is the angle between each covelent bond of ch4?
In a methane (CH4) molecule, the angle between each of the covalent bonds (C-H bonds) is approximately 109.5 degrees. This angle is due to the tetrahedral molecular geometry of methane, where the carbon atom is at the center of a tetrahedron with each hydrogen atom at a corner.
What is the shape and polarity of CF4?
CF4 has a tetrahedral shape with all four carbon-fluorine bonds arranged symmetrically around the central carbon atom. It is a nonpolar molecule because the dipole moments of the four carbon-fluorine bonds cancel each other out due to their symmetrical arrangement.
Four bonds of CCl4 are directed in space at an angle of?
109.54 0. This is the tetrahedral angle. The chlorine atoms are at the corners of a tetrahedron with carbon in the centre.
What molecular shape is water H2O?
Water is usually described as "bent". The angle between the oxygen-hydrogen bonds is about 105 degrees; the lone pairs "push" the hydrogens closer together than a perfect tetrahedral geometry (109.4 degrees).
What makes something Tetrahedral?
A tetrahedral shape is defined by having four equally spaced vertices connected by edges that form four triangular faces. This shape is characterized by having bond angles of approximately 109.5 degrees between adjacent bonds. In chemistry, molecules with a tetrahedral geometry often have four electron pairs around a central atom, resulting in a symmetrical and three-dimensional structure.
Name two elements that form tetrahedral shaped bonds?
oxygen and sulfur have two pairs of unshared electrons. These two pairs of unshared electrons serve as another attached atom for the shape of the molecule. Now the items making the points of tetrahedron are now limited to two. The angle between the hydrogens in water is about 105 degrees
Exaples of a substance with tetrahedral geometry?
Methane (CH4) is a common example of a molecule with tetrahedral geometry. In methane, the central carbon atom is bonded to four hydrogen atoms, arranged symmetrically in a tetrahedral shape with bond angles of 109.5 degrees.
