Which of the following combinations is most likely to exhibit chemisorption?
Non-polar gases on a non-polar solid.
Polar gases on a polar solid.
Non-polar gases on a polar solid.
Polar gases on a non-polar solid.
Chemisorption is more favourable when there are complementary interactions between the gas molecules and the solid surface. Polar gases have stronger interactions with polar solids, making chemisorption more likely in such cases.
