Chemistry - Hydrogen and Its compound Question with Solution | TestHub
A colourless odourless gas "X" with gas "Y" can be prepared by action of steam over hot coke on a surface of catalyst at high temperature. The same gas "X" used in hydrogenation of vegetable oils using suitable catalyst to give edible fats.
Which of the following is CORRECT for gas "X" and "Y"?
Options:
Answer:
Solution:
Gas is H₂ (used in hydrogenation), and gas is CO, produced via the water-gas reaction ().
Option A is incorrect: The bond strength of H₂ () is significantly higher than Cl₂ ().
Option B is incorrect: The cation CO⁺ has an exceptional bond order of 3.5, which is greater than N₂ (3.0).
Option C is correct: Hydrogen (H₂) boils at 20.3 K, which is a higher temperature than Helium, the lightest noble gas (4.2 K).
Option D is incorrect: Both hydrogen and carbon monoxide gases are only sparingly soluble in water.
