Best Answer

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.

All single bonds, in tetrahedral shape.


What is the molecular geometry if you have 4 single bonds around the central atom?

It 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.

What determines whether a carbon atom's covalent bonds to other atoms are in a tetrahedral configuration or a planar configuration?

the presence or absence of double bonds between the carbon atom and other atoms


What is the angle between bonds in fluorine molecule?

180 degrees


What is the correct molecular shape for NF3?

Trigonal Pyramidal - 107.5 degrees It has 3 bonds and one lone pair. With all 4 elements (the 3 covalent bonds plus the lone pair) you would think it was Tetrahedral, with 109.5 degrees between them, but because the lone pair is there, it pushes the other bonding electrons closer together and thus you have a smaller angle of 107.5 degrees and the different shape.


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 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 is the difference between tetrahedral and a pyramidal molecule?

a tetrahedral is a molecular shape with no lone pairs. the central atom forms 4 bonds with the other atoms around it. a pyramidal is a shape where the molecule has 1 lone pair and has only formed 3 bonds with the other atoms around it. i hope this made sense:)


Molecular shape of CCl4?

It is a tetrahedral because it has 4 bonds and no unshared pairs of electrons.

Examples of tetrahedral molecules?

There are many compounds that exhibit tetrahedral structure. Some of those compounds are carbon tetrachloride (CCl4), chloroform (CHCl3), and methane (CH4). Many compounds of carbon (those which don't contain double bonds) are tetrahedral in structure because carbon tends to form four single bonds.


What bond is formed in methane?

Methane is a molecule with covalent bonds. Then again, there are different types of bonds. To be specific, Methane is a tetrahedral molecule with covalent long single bonds.


What is bayer's strain theory?

Bayer's strain theory accounts for the strain in bonds within a ring compound. In a tetrahedral bond angle is 109.28 degrees. If none of the bonds are 3 in a ring chain isomer, then each angle will be of 60 degrees that is 109.28 degrees. That means there is a lot of strain. Strain order: 3>4>5~6>7>8>9

What molecular geometry exists when a central carbon atom bonds to four other atoms?

Tetrahedral


How does hybridization explain the bonding of methane?

CH4 has 4 hybrid orbitals. None of them contain a pair of electrons and all 4 of them contain an unpaired electron, which will form single bonds with the 4 hydrogen atoms making a tetrahedral shape with bonds 109.5 degrees apart.


Why is graphite a good lubricant and diamond is an excellent abrasive?

Graphite has weak bonds with a different structure while diamond has stronger bonds and a tetrahedral structure. :)


Why a tetrahedral molecule containing four identical bonds can never be a polar molecule?

If there are 4 identical bonds, then there are equal pulls on all four bonds. Equal pulls = non polarity.


What is the VSEPR of CCl4?

CCl4 is tetrahedral, with C acting as the central atom and creating four bonds, one with each Cl. The Cl atoms are at maximum distance from each other, which creates the tetrahedral shape. Bond angles in tetrahedral forms are 109.5.


Is CBr4 a polar covalent bond?

Carbon Tetrabromide has covalent bonds but it has a tetrahedral shape so its not polar.
