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.
The bond angles within a tetrahedral structure are approximately 109o.
Yes. Si bonds are tetrahedral.
All single bonds, in tetrahedral shape.
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.
the presence or absence of double bonds between the carbon atom and other atoms
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.
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.
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).
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:)
It is a tetrahedral because it has 4 bonds and no unshared pairs of electrons.
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.
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.
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

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.
Graphite has weak bonds with a different structure while diamond has stronger bonds and a tetrahedral structure. :)
If there are 4 identical bonds, then there are equal pulls on all four bonds. Equal pulls = non polarity.
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.
Carbon Tetrabromide has covalent bonds but it has a tetrahedral shape so its not polar.
