Electronegativity and strength acids and bases

Postby Samantha Chung 4I » Tue Dec 04, 2018 10:41 am

In the textbook 6C.3 (7th edition), it says that the stronger electronegativity values makes stronger hydronge bonds between H20 and H -A bond. But I thought that hydrogen bonds only apply to H bonded to O,N, and F within the same molecule. Can I assume then that the H bonded to O, N, and F is a condition for hydrogen bonding, but does not describe H bonding itself?

I think it relates to the fact that a greater electronegativity difference would result in more electrons being further away from the hydrogen giving it a stronger positive partial charge. It will then form stronger hydrogen bonds because of the charge difference.
