In hydrogen bonding there is a hydrogen bonded to either N,O,F. These are some of the most electronegative elements in the periodic table and therefore have great polarizing powers, making their bond with hydrogen very strong.
For hydrogen bonds and dipole-dipole bonds, you're looking at the strength of the bond between partially + and partially - atoms. Since N,O, and F usually bond with H in a hydrogen bond and they tend to be more electronegative, they'll result in a higher polarity against the positive hydrogen so the bond will be stronger as well.
Since it is bonded to N, O, or F, which are highly electronegative, H’s one electron will be pulled away from it. So that means H is basically just a proton and therefore negatively charged atoms will be highly attracted to it.
