Why is the boiling point of H2O much higher than h2se?
The boiling point of a substance is influenced by the strength of intermolecular forces between its molecules. In the case of H2O (water), it forms strong hydrogen bonds between molecules, resulting in a higher boiling point compared to H2Se (hydrogen selenide), which has weaker dispersion forces due to larger atomic size and lower electronegativity of selenium.
Which has a higher boiling point between H2O or H2Se?
Water has a higher boiling point than hydrogen selenide, because the strong hydrogen bonding of water gives it a higher "effective" molecular weight than hydrogen selenide, the unit that must be vaporized on boiling consisting on average of several water molecules rather than only one. The selenide, in contrast, forms only weak hydrogen bonds; therefore, its average "effective" molecular weight in essentially that of a single molecule.
Which has the highest boiling point H2S or H2Se or H2O?
Water has the highest boiling point, as the hydrogen bonds between the molecules need more energy to break than the hdyrogen bonds in H2S, and H2Se, as Oxygen is much more electronegative than Sulphur of Selenium, so it makes the molecules more polar.
Is H2Se a acid?
Yes, hydrogen selenide (H2Se) is an acid. It is a weak acid that dissociates in water to give off hydrogen ions.
What is the acid name H2Se?
H2Se is a stronger acid than H2S. The bond energy of H2Se is less than H2S, making it easier for the hydrogen atom to leave the molecule. Therefore, H2Se is expected to be a stronger acid than H2S.
What is the formula of the compound dihyrdogen selenide?
The correct formula is H2Se. Because it is an acid, hydrogen needs to be at the beginning. Hydrogen has an ionization of +1 and selenium (from which you get selenic) has -2, so you'll need 2 atoms of hydrogen (H) to balance out 1 atom of selenium (Se). So you'll have H2Se.
How many valence electrons does H2Se have?
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
Is H2Se an ionic bond?
No, as hydrogen-and selenium are both nonmetals the bonds are covalent.
How many dots in the Lewis Dot Structure of H2Se?
There are 16 dots in the Lewis Dot Structure of H2Se. Each hydrogen atom contributes 1 dot and selenium contributes 6 dots.
How many bonds can selenium have with hydrogen?
Hydrogen selenide (H2Se) has two bonds.
Is hydrogen selenide polar?
Hydrogen selenide is a polar compound.
Intermolecular forces that must be overcome to convert H2Se to gas?
The intermolecular forces that must be overcome to convert H2Se (hydrogen selenide) to gas are London dispersion forces and dipole-dipole interactions. These forces hold the H2Se molecules together in the liquid state. As energy is added to the system, these intermolecular forces weaken, allowing the molecules to overcome the attractive forces and transition into the gaseous state.
