Web24 feb. 2024 · According to the values of boiling points that I found on internet the order is as follows: H X 2 O > H F > N H X 3 I was expecting H F to have highest boiling point because F is the most electronegative atom hence should form stronger H Bonds. Now, I think the factor here might be number of H Bond rather than strength of H Bond.
