Is H2S stronger than HBr?
. H2Se, HBr HDr is the stronger acid because Dr is more electronegative than Se so Dr is more stable than HSe-.
Is H2Se a strong acid?
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.
Is HCl stronger than H2Se?
HCl is a stronger acid than H2S because Cl is more electronegative than S. H2O is a stronger acid than H2Se because O is more electronegative than Se. H2SO4 is a stronger acid than HSO4- because it has more acidic H atoms.
Is HBr a stronger acid than HCl?
In binary acids such as HBr and HCl, the H–Br bond is longer than the H–Cl bond as Br is larger than Cl. The H–Br bond is therefore weaker than the H–Cl bond and HBr is thus a stronger acid than HCl.
Which acid is stronger H2Se or HBr?
Yes, hydrogen bromide (HBr) is stronger than hydrogen selenide (H2Se).
Why is HBr an acid?
Explanation: In the Bronsted-Lowry definition, an acid is anything which donates H+ ions in an aqueous solution. Now, a strong acid is an acid which almost completely dissociates in aqueous solutions. HBr fulfils this, because it very readily dissociates—here’s why.
Why is HBr a stronger acid than HOBR?
If my understanding is correct, bromous acid (HBrO2) is a stronger acid than hypobromous acid (HBrO) because the additional electronegative oxygen atom draws the electron away from the hydrogen atom, making dissociation for H+ easier.
Is HCl or HBr more stable?
Atoms with more electronegativity hold the electrons more tightly and are more stable. By the above explanation, fluorine being the smallest and most electronegative element,it is said to be more stable. Hence,the order is HF > HCl >HBr >HI.
Is HCN a weak acid?
Weak acids, like strong acids, ionize to yield the H+ ion and a conjugate base. Because HCl is a strong acid, its conjugate base (Cl−) is extremely weak….Strong and Weak Acids and Acid Ionization Constant.
| Acid | Conjugate Base |
|---|---|
| HCN (hydrocyanic acid) (weakest) | CN− (cyanide ion) (strongest) |
