tetrachloromethane is correct. why ?
A. It is used as cleaning fluid.
B. It is used as degreasing agent
C. It is used in pharmaceutical industry
and so on...
tetrachloromethane and trichloromethane are used in dry cleanin industries
tetrachloromethane is a degreasing agent
The answer to this question is C
Why?
Trichloromethane(CHCl3) is a colourless liquid, immiscible with water, non-inflammable but toxic. It is used as an anasthestic in preserving biological specimen and as a solvent for fats,greases and waxes while tetrachloromethane is used in laundry to remove stains and in fire extinguishers so the correct answer is C
*From ChatGPT*
Dichloromethane, also known as methylene chloride (CH₂Cl₂), is widely used in modern industrial applications as a degreasing agent. Its effectiveness stems from its ability to dissolve a wide range of organic compounds, making it suitable for cleaning and degreasing purposes in various industries, including electronics and metal processing.
In contrast, tetrachloromethane (carbon tetrachloride, CCl₄) was historically used for degreasing but has been largely phased out due to its toxicity and ozone-depleting properties. Its current use is limited to specific applications under strict regulations.
Therefore, considering current industrial practices and safety standards, dichloromethane is the chlorinated alkane most commonly used today for removing grease.
The chlorinated alkane commonly used for removing grease is **trichloroethylene** (TCE) or **tetrachloroethylene** (also known as perchloroethylene, PERC). These compounds are effective solvents for cleaning and degreasing due to their ability to dissolve a wide range of substances, including oils and greases. However, it's important to note that both TCE and PERC are subject to environmental regulations because of their potential health risks and environmental impact. Proper safety precautions should be taken when using these solvents.
I'll pick an answer and when it time to submit my answer will be changed and it's almost all the question that I attempted
