Answer:
The hydrogen bond between hydrogen fluoride molecules is stronger because the polarization in H-F molecule is stronger.
Explanation:
The more polarization happens in the molecule the stronger the inter-molecular hydrogen bond is.
Consider water (H - O - H) and hydrogen fluoride (H - F), the polarization of the (H - F) bond is stronger than the (O - H) bond due to the higher electronegativity of the fluoride atom. Actually, fluoride has the highest electronegativity.
Aniline has smallest Rf value on silica gel since it is more polarthan the other compounds because aniline is a hydrogen donor and acceptor itmakes the molecule more attracted to the silica gel which is also also polar as<span>‘likes dissolve likes.’</span>

Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend.
This answer is 24 because 2.17 x 10 -8 is 24 so that would be your answer
