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.
What else can I help you with?
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 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 an ionic bond?
No, as hydrogen-and selenium are both nonmetals the bonds are covalent.
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 polarity of H2Se?
H2Se is a polar molecule due to the difference in electronegativity between hydrogen and selenium atoms. This causes an uneven distribution of charge, resulting in a slightly negative end near selenium and a slightly positive end near hydrogen.

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.
What is the polarity of H2Se?
H2Se is a polar molecule due to the difference in electronegativity between hydrogen and selenium atoms. This causes an uneven distribution of charge, resulting in a slightly negative end near selenium and a slightly positive end near hydrogen.
How many valence electrons does H2Se have?
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
What is the name of the covalent bond H-2Se?
The covalent bond between hydrogen and selenium is known as a hydrogen-selenium bond.
Why boiling point of H2O is greater than H2S?
Although both molecules are polar and have similar masses, the O-H bond in water is highly polar, producing a dipole movement in the overall molecule towards O. The S-H is also polar and produces a dipole movement towards S, but it is not as strong a separation of charge as that produced by O-H. This results in H20 molecules being more strongly attracted to each other by Hydrogen bonding, than H2S molecules which are attracted to each other due to only dipole-dipole attraction. Stronger attraction between molecules means it takes more energy to separate them into the gas phase, making it have a higher boiling point.
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.
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.
