Hint:Before determining the strength of each type of bonding, it is important to know that there are two types of attraction in between molecules and are intramolecular and intermolecular. Hydrogen bonding and dipole dipole interactions are both intermolecular in nature.
Complete answer:
Dipole-dipole interactions generally occur when partially negatively charged molecules interact with a neighbouring molecule that is positively charged. For such bondings to happen, the ions must be charged. Hydrogen bonding, on the other hand, is a special type of dipole-dipole bonding.
Such type of bonding happens especially when a hydrogen atom is bonded to either a nitrogen, oxygen or fluorine atom. When the partially positive;y charged hydrogen atom comes in contact with a neighbouring partially negatively charged fluorine, nitrogen or oxygen atom, hydrogen bonding takes place.
As hydrogen is a special case of Dipole-dipole interactions and we know that it is an electrostatic attraction, the hydrogen bonding becomes the strongest of all dipole-dipole interactions as the fluorine, nitrogen or oxygen atoms are much more electronegative than hydrogen which makes the polarity of the bond extra strong. With such a high difference in the electrostatic behaviour and such strong polarity, the bonding becomes extra strong and thus Hydrogen bonding is stronger than dipole-dipole interactions.
Note: Both dipole-dipole and hydrogen bonding happen between atoms of two different molecules and not between atoms of the same molecules. Which is the main difference between intramolecular bonding and intermolecular bondings like dipole-dipole and hydrogen bondings.
