Question

Find the maximum possible number of hydrogen bonds in which $H_2{O}_2$ molecule can participate.

Answer 1

The maximum possible number of hydrogen bonds in which $H_2{O}_2$ molecule can participate is $6$. Each $H$ atom can form one hydrogen bond.

Thus, two hydrogen atoms forms two hydrogen bonds. Each oxygen atom can form $2$ hydrogen bond.

Thus, two oxygen atoms can form $4$ hydrogen bonds. Thus, total $6$ hydrogen bonds can be formed by on molecule of hydrogen peroxide.
