Hydrogen bonding is an intermolecular force, while bonds are intramolecular forces and occur inside of molecules in the form of bonds. They all rely on the same fundamental forces, but are technically different things.

is this ascending or descending in strength?
this is in decreasing strength. hydrogen bonds are the strongest and LDF /induced dipole forces are the weakest
A Hydrogen bond is a weak bond resulting from the proton's electrostatic attraction in one atom and the electronegativity of another atom. A pi bond is a covalent bond between the unbound p-orbitals of two atom's and restricts the rotation of the atoms.

hydrogen bonding is a type of intermolecular force whereas pi bonds are the means by which the bond is formed. However, I'm not sure hydrogen bonding and pi bonds coexist as hydrogen only forms single bond hydrogen bonds whereas pi bonds are only present in double and triple bonds
