In this solution water is a polar molecule whereas oil behaves as a non-polar molecule. These two molecules do not form a solution as they cannot be mixed up.

Covalent drugs block protein function by forming a specific bond between the ligand and target protein.

What causes covalent bonds to form. Halogen bonding is a type of non-covalent interaction which does not involve the formation nor breaking of actual bonds but rather is similar to the dipoledipole interaction known as hydrogen bondingIn halogen bonding a halogen atom acts as an electrophile or electron-seeking species and forms a weak electrostatic interaction with a nucleophile or electron-rich species. Nucleotides are building blocks of nucleic acids DNA and RNAA nucleic acid contains a chain of nucleotides linked together with covalent bonds to form a sugar-phosphate backbone with protruding nitrogenous bases. In a solution a polar molecule cannot be mixed with the non-polar molecule.

A covalent mechanism of action can provide many pharmacological advantages over a reversible. For example DNA contains two such chains spiraling round each other in the famous double helix shape. For example consider water and oil.

Examples of Polar and Non-Polar Molecules A molecule may be polar or non.
