Molecular Shapes Essay
Many molecules have shapes that are different to other molecules. The 5 most important molecules are tetrahedral, pyramidal, bent, linear, and trigonal planar. These shapes make up 5 different molecules.
Firstly, an example of tetrahedral shape is methane. This molecule's hybridization is sp3. Almost all tetrahedral-shaped molecules tend to have a hybridization of sp3. This molecule is a non-polar molecule. It also has a non-polar covalent bond. This molecule has a degree of 109.5.
Secondly, an example of a pyramidal-shaped molecule is ammonia. There is no hybridization for this molecule. This molecule is a polar molecule with a polar covalent bond. The degree of this molecule is 107.
Next, one of the many examples of a bent-shaped molecule is water. The hybridization of this molecule is sp3. This molecule is a polar molecule. All bent-shaped molecules are polar molecules. This molecule has a polar covalent bond. This molecule is 105 degrees.
After that is an example of a linear-shaped molecule which is carbon dioxide. This molecule has a hybridization of sp. It is a non-polar molecule with a double polar covalent bond. It has a degree of 180.
Finally, an example of a trigonal-shaped planar molecule would be boron trihydride. The hybridization of this molecule is sp2. This is a non-polar molecule with non-polar covalent bonds. The degree of this molecule is 120.
In conclusion, there are many shapes of molecules. The most common ones are tetrahedral, pyramidal, bent, linear, and trigonal planar. Each of these shapes are different molecules with different bonds, hybridizations, and degrees.
