Which is stronger acid HOI or HOCl?

HOCl is the stronger acid because its Ka value is greater than the Ka value of HOBr. HOI is a weaker acid than HOCl because the O–H bond in HOI is stronger than the O–H bond in HOCl.

Why HOCl is more acidic than HOBr?

The chlorine is more electronegative than bromine. As a result, it will attract electrons more towards itself than bromine. This will result in a donation of H+ more easily in HOCl than in HOBr. So, the HOCl will be stronger acid than HOCl.

Which of the following order of acid strength is correct HOI HOBr HOCl?

Thus fluorine is the element with higher electronegativity and thus HOF will be the strongest acid and iodine has lowest electronegativity and therefore HI will be the weakest acid.

Is HOBr a stronger acid?

The weaker the O–H bond, the stronger the acid. Cl is more electronegative than Br so HOCl is stronger acid than HOBr. 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 is the strongest Hypohalous acid?

Greater the stability of the conjugate base, stronger is its acid. From here, we can conclude that the order of acidity in hypohalous acids is: HClO > HBrO > HIO. Therefore, the answer is – option (a) – HClO is the most acidic hypohalous acid.

Which of the following is strongest acid HOCl?

In the last we can conclude that the strongest acid is HClO4. Hence, the correct option is (D).

What is the strongest acid among the following?

perchloric acid
The strongest acid is perchloric acid on the left, and the weakest is hypochlorous acid on the far right. Notice that the only difference between these acids is the number of oxygens bonded to chlorine. As the number of oxygens increases, so does the acid strength; again, this has to do with electronegativity.

Which of the following acid is the strongest?

The strongest acid is perchloric acid on the left, and the weakest is hypochlorous acid on the far right. Notice that the only difference between these acids is the number of oxygens bonded to chlorine.

Is h3aso4 a strong acid?

Oxoacids are weak, if the difference between the number of oxygen atoms and ionizable hydrogen atoms is less than or equal to 1. has three ionizable hydrogen atoms and four oxygen atoms. Hence, it is a weak acid.

How to increase acid strength Hof, HOCl, Hoi?

Arrange the following : Increasing acid strength HOF, HOCl, HOBr, HOI. Increasing acid strength HOF, HOCl, HOBr, HOI. Increasing oxidising power F2, Cl2, Br2, I2. Increasing acid strength HF, HCl, HBr, HI.

Which is stronger acid, HClO4 or HIO4?

As another answer pointed out, HClO4 is the strongest acid in the series because the negative charge on the conjugate base (ClO 4 −) is resonance-stabilized over all four oxygens. Why do you combine acid strength and oxidizer strength into a single property as if they are destined to be the same? They are not.

How is acidity measured in HClO3 and HBrO3?

Acidity can be measured as the easy of releasing a proton (H+) unit. 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.

How is the acid strength of an oxoacid determined?

An oxoacid is an acid that contains oxygen. Discuss the periodic trends that help determine oxoacid strength. The central atom ‘s electronegativity and the number of oxygen atoms determines oxoacid acidity. Carboxylic acids are an important subclass of organic oxoacids and the most common type of organic acid.

Which is stronger acid HOI or HOCl? HOCl is the stronger acid because its Ka value is greater than the Ka value of HOBr. HOI is a weaker acid than HOCl because the O–H bond in HOI is stronger than the O–H bond in HOCl. Why HOCl is more acidic than HOBr? The chlorine is…
