Chemistry - Hydrogen and Its compound Question with Solution | TestHub
Based on the nuclear spin, hydrogen shows two types of isomers(i) ortho hydrogen (ii) parahydrogen. ortho hydrogen, molecular form of hydrogen has same spin of proton, where as in para hydrogen, the molecular form of hydrogen has opposite spin of proton.
At room temperature a mixture of ortho and para hydrogen is taken for experiment now temperature of this mixture is reduced to (very low). then final mixture will contain -
Options:
Answer:
Solution:
Hydrogen exists as ortho- and para- forms based on nuclear spin. At room temperature, the equilibrium mixture is 75% ortho and 25% para. However, the para form is more stable at very low temperatures. As the temperature is reduced to , the equilibrium shifts almost entirely towards the para form. Therefore, the final mixture will contain almost exclusively para hydrogen.
The final answer is
