Answer 1

Hint: We must know that the chlorine is a chemical element with the symbol $Cl$ and it has 17 electrons in orbitals. Chlorine is second-lightest of the halogens; it appears between fluorine and bromine in the periodic table. Chlorine is a yellow-green gas at room temperature.The liquid chlorine is found to have a characteristic green colour.

Complete step by step answer:
Let’s start with discussing a little about the chlorine gas to get a better understanding regarding the question. Chlorine gas is used in many places and for easy storage and transfer it is being cooled and pressurized into the liquid form. When the liquid turns into the gas, the gas has a characteristic yellow green colour with the irritating odour. It is to be noticed that since the chlorine gas is heavier than the atmospheric air, it generally gets deposited in low lying areas.
In the question we have been asked regarding the colour of the chlorine gas. As stated above the colour of the chlorine gas is yellow green. The options that are provided to us contain the colours Red, purple, orange, green and blue. Out of all these options only one option i.e. green is correct.

So, the answer to this question is option D. green.

Additional Information:
Chlorine has been used in industry for a very long time. It has been used for making PVCs, chloroform, dichloromethane and many more chemical reagents. It is also being used to develop insecticides, bactericides and used in the textile and printing industry as well.

Note:
 We have to know that chlorine gas is found to be deadly in many cases and if leaked can cause a lot of problems hence is being used with a lot of precautions and regular checks are being done. This gas is irritating and has immediate solubility in water. Due to its immediate solubility in water it can easily contaminate the water. Also this gas causes acute damage to the upper and lower respiratory tract.
