- A Carbon tetrachloride is used as a preservative for anatomical specimens
- B Dichloromethane is used as a solvent in drug industry
- C Freon-12 acts as a propellant in aerosol sprays
- D DDT is useful to protect crops and to kill mosquitoes that spread malaria
Answer & Solution
Correct Answer
(A) Carbon tetrachloride is used as a preservative for anatomical specimens
Step-by-step Solution
Detailed explanation
Carbon tetrachloride is primarily used as a solvent for oils, fats, lacquers, varnishes, rubber waxes, and resins. It is also used as a fire extinguisher under the name Pyrene. It is not used as a preservative for anatomical specimens; formaldehyde is commonly used for that…
