What is the molecular geometry of SeH2?
Bent.
What is the name of this chemical formula - SeH2?
Hydrogen Selenide and it is extremely toxic when inhaled.
What type of selenium hydride?
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.
What type or types of inter-molecular forces are expected between SeH2 molecules?
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.
Why is SeH2 linear and not bent?
The molecule should have 2 atoms with 2 lone electron pairs and be in bent configuration.
What is the chemical name for SeO?
Selenium http://www.chemicalelements.com/elements/se.html
Why is SeH2 linear and H2O is bent?
SeH₂ is linear because the selenium atom has a lower electronegativity than oxygen, resulting in a less pronounced lone pair-bonding pair repulsion. In contrast, H₂O has two lone pairs on the oxygen atom, which exert greater repulsion on the bonded hydrogen atoms, pushing them closer together and creating a bent molecular geometry. Additionally, the bond angles in water are influenced by the tetrahedral arrangement of electron pairs, leading to a bond angle of about 104.5 degrees.
