The bonds can be arranged in increasing order of polarity as follows: C-H < N-H < O-H < F-H. This is because fluorine is the most electronegative element, making the F-H bond the most polar, followed by the O-H bond due to the high electronegativity of oxygen. Nitrogen is less electronegative than oxygen, so the N-H bond is less polar than the O-H bond. Lastly, carbon is the least electronegative element in this series, making the C-H bond the least polar. **

Only H and H receive because they are the only two individuals who have been identified as the recipients of whatever is being given.

"H" is always written as "h" because it is the standard way to represent the sound that the letter "h" makes in the English language.

Only H and H are receiving because they are the only ones involved in the specific situation or transaction being referred to. It could be that they are the only ones who are directly impacted by the outcome, or that they are the only ones who have a stake in the matter at hand. The decision to only involve H and H in the receiving process could be based on their specific roles, responsibilities, or involvement in the situation. **
