Here are the essential concepts you must grasp in order to answer the question correctly.
Skeletal Structure
A skeletal structure is a simplified representation of a chemical compound that shows the arrangement of atoms and bonds without depicting all the hydrogen atoms explicitly. In skeletal formulas, carbon atoms are represented by vertices or ends of lines, while bonds between them are shown as lines. This method allows chemists to visualize complex molecules more easily and is particularly useful for organic compounds.

Refrigerants
Refrigerants are substances used in cooling systems, such as air conditioners and refrigerators, to absorb heat and provide cooling. They undergo phase changes from liquid to gas and back, facilitating heat transfer. The choice of refrigerant is crucial due to its efficiency, safety, and environmental impact, as some refrigerants can contribute to ozone depletion and global warming.
Environmental Impact of Chemicals
The environmental impact of chemicals refers to the effects that chemical substances have on ecosystems, human health, and the atmosphere. Compounds like 1,1,1,2-tetrafluoroethane can contribute to greenhouse gas emissions and ozone layer depletion, prompting regulatory actions to phase out harmful substances. Understanding these impacts is essential for developing sustainable alternatives and protecting the environment.
