Question

${\mathrm{CCl}}_4$cannot be used as______

Answer 1

${\mathrm{CCl}}_4$ cannot be used as an insecticide.

Carbon tetrachloride was first prepared in 1839. German-born French scientist Henri Victor Regnault discovered it during his work with ether/chlorine reactions.

• Carbon tetrachloride is used for dry cleaning, degreasing metals, fumigating, and manufacturing refrigerants and aerosol propellants.
• It is used as a component in the manufacture of lava lamps.
• In NMR spectroscopy.
• ${\mathrm{CCl}}_4$ acts as a solvent that is actually used for the smooth conduct of the reaction.
• Nowadays carbon tetrachloride is also used as a fire extinguisher as an alternative to carbon dioxide.

Thus, ${\mathrm{CCl}}_4$ cannot be used as an insecticide.
