Tetrahedral carbon compounds
In saturated organic compounds, all of the carbon atoms are tetrahedral.
Chloroalkanes
- A chloroalkane is an alkane in which one or more hydrogen atoms are replaced with chlorine atoms.
- Chloroform (
- ) is an example of a chloroalkane.
- Chloroalkane’s main uses:
- For removing oil and grease marks from machinery and in dry cleaning of clothes.
- Paint stripper.
- Correcting fluid, e.g. Tippex.
Alcohols
- The alcohols form a homologous series of organic compounds, of general formula
- .
- The -OH group is called the hydroxyl group and is the functional group of alcohols.

Answer
LC Chemistry
Pi bonds are usually weaker than sigma bonds. Quantum mechanics says this is because the orbital paths are parallel so there is much less overlap between the p-orbitals. Pi bonds happen when two atomic orbitals are in contact through two areas of overlap. Pi-bonds are more spread out bonds than the sigma bonds.
