Question

NH, is easily liquified than HCI. Explain​

Answer 1

Answer:

The liquifaction of a gas depends upon its critical temperature that is minimum temperature above which a gas can not be liquified even after applying very high pressure also.

Higher the critical temperature, more easily the gas can be liquified.

Ammonia has higher critical temperature than HCl.

Hence, ammonia is more easily liquefiable than HCl.

Explanation:

Answer 2

• The liquifiablity of a gas depends on various factors such as temperature, pressure and the type of bonds present in the molecule. A gas is more easily liquified at lower temperatures and high pressures.
• It also depends on the critical temperature of a substance which is the minimum temperature above which a gas cannot be liquified. Higher the critical temperature, easier is the liquification process.
• In case of NH₃ molecules, the hydrogen bonds make the liquefying process easier by pulling the molecules together. NH₃ also has a higher critical temperature than Hal.
• However, in the case of Hal, liquification becomes difficult due to the big size of Cl atoms. Hal has lower critical temperature than NH₃.
• Hence, NH, is easily liquified in comparison to HCI.
