Which is more acidic HClO3 or HClO?
Most acidic: HClO4 > HClO3 > HClO2 > HClO. For a series of oxyacids with the same number of oxygens but with different central atoms such as HOBr, HOCl, HOI, as the electronegativity of the central atom increases, the O-H bond strength weakens and the acidity increases.
Which is more acidic hbro3 or HBrO2?
Ernest Z. HBrO2 is the stronger acid.
Which one is more acidic HClO4 or HClO3?
HClO4 is a stronger acid than HClO3 .
Why is HClO more acidic than HIO?
HCl is a weaker acid than HBr and HI due to the greater radii of Br and I, but why is HClO more acidic than HIO? Because Cl is more electronegative, it is more acidic.
Why is HClO3 more acidic?
– In Chlorous acid, Cl=O. bond will withdraw the electron density from the negatively charged oxygen atom in the conjugate base, so the conjugate base will be more stable and hence the overall acidic strength of Chlorous acid will be more compared to Hypochlorous acid.
Which acid hio2 or hbro3 is stronger?
Since HBrO3 has greater electronegative nonmetal and more oxygens than HIO2, HBrO3 will be more acidic.
Why is HBrO2 weaker than HClO2?
So the electron of O – H bond strongly attract Cl atom towards itself than bromine atom . As a result the O -H bond in HClO2 is more polar than O -H bond in HBrO2 . Hence HClO2 released proton easily than HBrO2 . Consequently , HClO2 is more stroger acid than HBrO2 .
Which is more acidic P2O3 or SO2?
d : Acidity of the oxides of non metals increases with the electronegativity and oxidation number of the element. Al2O3 < SiO2 < P2O3 < SO2Al2O3 is amphoteric. SiO2 is slightly acidic whereas P2O3 and SO2 are the anhydrides of the acids H3PO3 and H2SO3.
Which is more acidic HClO4 or HBrO4?
In fact, perchloric acid is usually considered as the strongest of all simple acids. Among oxoacids of elements of the same group having similar composition, acid strength increases as electronegativity increases. Since chlorine is more electronegative than bromine, HClO4 is a stronger acid than HBrO4.
Why HClO is more acidic than HBrO?
HBrO . In direct contrast with HCl vs. HBr , HClO is a stronger acid than HBrO , because Cl is more electronegative, which dominates over the size difference between Cl and Br due to the presence of the oxygen.
How do you arrange HClO3 HBrO3 and HIO3 in order of acidic strength?
Arrange HClO3, HBrO3 and HIO3 in the order of acidic strength. in the order of acidic strength. C l,Br,I all, belong to the same group. As one goes down the group, the atomic size increases and electronegativity decreases. Electronegativity is the ability of an atom to pull electrons towards itself.
How many oxygen atoms are present in HClO3 and HBrO3?
Comparing HClo3 and HBrO3 there are 3 oxygen atoms bound to the central halogen in each case causing a shift of electrons from the halogens to the oxygen. But halogens are electronegative and don’t like their electrons getting pulled from them.
Which is stronger HClO or HClO3?
HClO3 is stronger than HClO. because as the number of oxygen atom increase the acid becomes more stronger. Which is the strongest acid among HOCl, HOBr, and HOI?
What is the difference between HCl and HBrO?
1 Answer. Of these, the only ones that are conceptually reasonable to explain are HClO vs. HBrO. In direct contrast with HCl vs. HBr, HClO is a stronger acid than HBrO, because Cl is more electronegative, which dominates over the size difference between Cl and Br due to the presence of the oxygen.
