Hydrogen selenide has two hydrogen atoms attached to a selenium atom in a bent configuration. This forms an H-Se-H with a bond angle of 91 degrees.
Bent.
Hydrogen Selenide and it is extremely toxic when inhaled.
There are several types of selenium hydrides based on the number of selenium atoms bonded to hydrogen, such as hydrogen selenide (H2Se), selenium dihydride (SeH2), and diselenium tetrahydride (Se2H4). Each compound has distinct properties and reactivity.
SeH2 molecules experience dipole-dipole interactions due to the polar nature of the molecule, where the selenium atom is more electronegative than the hydrogen atoms. Additionally, London dispersion forces (van der Waals forces) are also present, which occur due to temporary dipoles that can form in all molecules. The combination of these forces contributes to the overall intermolecular interactions in SeH2.
The molecule should have 2 atoms with 2 lone electron pairs and be in bent configuration.
