What is the molecular geometry of SeH2?
What is the molecular geometry of SeH2?
The molecular geometry of SeH2 is bent with asymmetric charge distribution on the central atom. Therefore this molecule is polar. Hydrogen Selenide on Wikipedia.
What is the bond angle of H2Se?
D. 109˚

What type of bond is H2Se?
H2S, H2Se and H2Te exhibit dipole-dipole intermolecular forces while H2O exhibits hydrogen bonding. In this case the hydrogen bonding of water is stronger than the dispersion of H2Te.

Is H2Se an acid or base?
In binary acids such as H2S and H2Se, the H–Se bonds is longer than the H–S bonds as Se is larger than S. The H–Se bond is therefore weaker than the H–S bond and H2Se is thus a stronger acid than H2S. The order is therefore H2O < H2S < H2Se < H2Te.
Is C2H3O2H an acid or base?
C2H3O2H acetic acid H2CO3 carbonic acid.
Is Cl or Br more basic?
So if fluorine were the most electronegative in terms of acidity, it would be the opposite in terms of base classification. The F would be the strongest base, followed by the Cl, the Br, and lastly, the I.
Which acid is stronger H2Te or H2Se?
Among H2S, H2Se, H2Te the strongest acid is H2Te. The reason being that the bond strength in it the weakest so it dissociates easily.
Is HClO a strong acid?
seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.) 2. solutions of weak acids have a low concentration of H+.
Why is HOBr weaker HBrO3?
HOBr is a weaker acid than HBrO3. The number of oxygen atoms will effect the strength of the acid. HOBr has a single oxygen atom while HBrO3 contains three.
Which is the strongest acid HClO4?
perchloric acid
Is HClO2 or HClO3 a stronger acid?
The general rule is that the acid is stronger if it has more O atoms in a series such as this. HClO4, perchloric acid, is a very strong acid as is HClO3. HClO2 is a weak acid and HClO is even weaker. HClO3 (chloric acid) is a stronger acid than HClO2 (chlorous acid) for the following reason.
Is HClO4 stronger than HClO2?
As the number of oxygens increases as you go from HClO to HClO4, the oxidation number of Cl increases. The oxidation number for Cl in HClO is +1, +3 for HClO2, +5 for HClO3, and +7 for HClO4. This is why HClO4 will be the strongest acid.
Is HBrO3 a strong acid?
There are only 6 strong acids: HClO4 perchloric acid. HNO3 nitric acid. HF (Hydrofluoric acid) is a weak acid, but you can’t store it in glass bottles as it will dissolve the glass. So, no, since HBrO3 and HBrO4 don’t completely dissociate, they are not considered strong acids.
Is H2SO4 stronger than H2SO3?
H2SO4 has 2 displacable H-ions and H2SO3 has 2 displacable H-ion. And the strength of an acid can be measured by the number of displacable hydrogen ion it gives and how stable its conjugate base will be. Thus, H2SO4 is stronger than H2SO3.
Why is sulfurous weak?
Unlike sulphuric acid (H2SO4), sulphuric acid (H2SO3) is a weak acid; that is, aqueous sulphuric acid does not dissociate entirely into H+ (H3O+) and bisulfite ions, meaning that the bisulfite ion is comparatively stronger in maintaining a proton when there is a base, such as water.
Why is H2SO3 stronger than H2SeO3?
Sulfur is more electronegative than selenium. Therefore it attracts oxygen’s electrons more strongly and weakens the O-H bond to a greater extent, enabling H+ to be released more easily. Because selenium is larger than sulfur, its valence orbitals are more diffuse. …
Is H3AsO4 stronger than H3AsO3?
H3AsO4 (arsenic acid) is a much stronger acid than H3AsO3 (arsenous acid). The first pKa for arsenic acid is 2.2 while for arsenous it is 9.2. Since pKa are logarithmic Arsenic acid a ten million times more acidic than arsenous acid.
Why is HClO4 a stronger Oxyacid than H2SeO4?
2:. :H2SO4 and HClO4,HClO4 is strong because the perchlorate ion form by the removal of hydrogen atom is more stabilised than sulfate ion or in othr words the negtive charge in perchlorate ion is more dispersed as compared to sulfate ion.
