Which of the following petroleum products is used as a solvent for dry cleaning clothes?

The petroleum product commonly used as a solvent for dry cleaning clothes is perchloroethylene, also known as PERC. It is a chlorinated hydrocarbon that effectively removes stains and dirt from fabrics without the use of water. PERC has been widely used in the dry cleaning industry due to its ability to dissolve oils, greases, and wax, making it an ideal cleaning agent for various types of textiles.

While PERC is effective, there have been concerns about its environmental impact and potential health risks, leading some dry cleaners to seek alternative solvents that are less harmful. Other petroleum-based solvents that may also be used include hydrocarbon solvents, but they are generally less effective than PERC in cleaning clothes.

In summary, perchloroethylene (PERC) is the preferred petroleum product used in the dry cleaning process for its efficient stain removal properties.
