Q60 / 180 · NEET 2019 (Odisha) · Chemistry

The liquified gas that is used in dry cleaning along with a suitable detergent is

  • A
    water gas
  • B
    petroleum gas
  • C
    $\mathrm{NO}_2$
  • Correct answer
    D
    $\mathrm{CO}_2$

Solution

Solvents used to dry clean clothes are usually chlorinated compounds which are carcinogenic. Suitable detergents which work in liquid carbon dioxide have been discovered to replace the chlorinated compounds. Thus, $\mathrm{CO}_2$ is the liquified gas that is used in dry cleaning along with a suitable detergent.

Hence, the correct answer is option: 'D'.
