# Which of the following is the correct order for the strength of hydrogen bonding

$\begin{array}{1 1}(a)\;SH....S > SeH.....Se > OH.....O\\(b)\;SeH....Se > SH.....S > OH.....O\\(c)\;OH....O > SeH.....Se > SH.....S\\(d)\;OH....O > SH.....S > SeH.....Se\end{array}$

$OH....O > SH.....S > SeH.....Se$
Here $O$-atom has the highest electronegativity value,forms the strongest H-bonds
Hence (d) is the correct answer.
