Which one of the following pairs is not correctly matched?a)Dry ice : ...
Explanation:
In this question, we are given a list of pairs and we have to identify the pair that is not correctly matched. Let's analyze each option one by one.
a) Dry ice: Solid carbon dioxide:
This pair is correctly matched. Dry ice is the solid form of carbon dioxide. It is called "dry ice" because it does not melt into a liquid state but directly sublimates into a gas when heated.
b) Mustard gas: Poisonous liquid used in chemical warfare:
This pair is also correctly matched. Mustard gas is indeed a poisonous liquid that has been used in chemical warfare. It is a powerful vesicant, causing severe blistering of the skin, eyes, and respiratory tract.
c) Teflon: Polymer containing fluorine:
This pair is correctly matched. Teflon is a brand name for a type of polymer called polytetrafluoroethylene (PTFE). It is a synthetic fluoropolymer of tetrafluoroethylene and is known for its nonstick properties.
d) Fullerene: Organic compounds containing fluorine:
This pair is not correctly matched. Fullerene is a molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube. It does not contain any fluorine atoms. Fullerene molecules can have different shapes, such as buckyballs (spherical) or nanotubes (cylindrical).
Conclusion:
Out of the given options, the pair "Fullerene: Organic compounds containing fluorine" is not correctly matched. Fullerene is a carbon-based molecule and does not contain any fluorine atoms.
