SUMMARY
The bent shape of Hydrogen Selenide (H2Se) is attributed to its six valence electrons, where two are used for bonding with hydrogen atoms and the remaining four exist as two lone pairs. The repulsion between these lone pairs is stronger than that between the bonding pairs, causing the bonding pairs to be pushed closer together. This results in a bond angle less than 180°, contrary to the tetrahedral arrangement seen in molecules like methane. The electron geometry of H2Se is similar to that of water (H2O), with the lone pairs influencing the molecular shape significantly.
