Editing Hydrogen peroxide (section)

===Comparison with analogues===
Hydrogen peroxide has several structural analogues with {{chem2|H_{''m''}X\sXH_{''n''}|}} bonding arrangements (water also shown for comparison). It has the highest (theoretical) boiling point of this series (X = O, S, N, P). Its melting point is also fairly high, being comparable to that of [[hydrazine]] and water, with only [[hydroxylamine]] crystallising significantly more readily, indicative of particularly strong hydrogen bonding. [[Diphosphane]] and [[hydrogen disulfide]] exhibit only weak hydrogen bonding and have little chemical similarity to hydrogen peroxide. Structurally, the analogues all adopt similar skewed structures, due to repulsion between adjacent [[lone pair]]s.
