Carbon Tetrachloride Polarity and Conductivity

  • Carbon Tetrachloride is non-polar and has a very low dipole moment.
  • Carbon Tetrachloride has a very low conductivity of 0.1036 W/m·K (300 K) as it does not dissolve in water too.

Carbon Tetrachloride Reaction with Acid

Carbon Tetrachloride is involved in a reaction with phenol in presence of Sodium hydroxide where Salicylic acid is formed along with Sodium chloride and water. The carboxylic group is always attached to the ortho-carbon with respect to phenolic -OH.

Reaction of Carbon Tetrachloride with Phenol

Carbon Tetrachloride Reaction with Base

In presence of excess aqueous potassium hydroxide, carbon tetrachloride decomposes to give carbonate ions, chloride ions in water. It is reported OHions act as a nucleophile to attack the carbon atom of carbon tetrachloride.

  • CCl4 + 6KOH = K2CO3 + 4KCl + H2O

Carbon Tetrachloride Reaction with Oxide

Carbon tetrachloride reacts with alkaline earth metal oxides to primarily evolve carbon dioxide at slightly room temperature where no chemical reaction has been predicted.


Carbon tetrachloride is a toxic colourless chemical widely used as a refrigerant or cooling agent in fire extinguishers. However, it’s need is restricted due to its involvement in ozone layer depletion. It can be a product of different chlorination reactions and decomposes in presence of sunlight.
