Which of the following represents the chemical formula for sulphur hexafluoride?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. SF₆.
The chemical formula for sulphur hexafluoride is SF₆. It consists of one sulphur (S) atom and six fluorine (F) atoms, forming a stable, colorless, odorless, and non-toxic gas under standard conditions. SF₆ is known for its high density and excellent insulating properties, making it widely used in the electrical industry, especially in gas-insulated switchgear (GIS) and circuit breakers. It is chemically inert and non-flammable, but it is also a potent greenhouse gas with a global warming potential much higher than carbon dioxide. Because of this, its usage is regulated in many countries to prevent environmental harm.
