Question

Arrange the following as stated.
-Increasing strength of hydrogen bonding ( X - H-X ).
$O,S,F,Cl,N$

Answer 1

Strength of hydrogen bonding in X -H- X depends on
electronegativity as well as size of X . X with higher
electronegativity and smaller size forms stronger H-bond
. Hence, increasing order of strength of H-bond is
S
