O , F , Cl , N in order of increasing strength of hydrogen bonding ?

Solution
The hydrogen bonding occurs due to electromagnetic attraction between a polar H-atom and an electronegative atom in a species.
So higher the electronegativity, stronger will be the bonding and so the order of bonding will follow,
F>O>N>Cl
as the electronegativity is also in order of F>O>N>Cl
However, the value of electronegativity is same for N and Cl (3.0) but the bonding is stronger in Nitrogen due to smaller size of N-atom which makes a stronger H-bond.
