What is the strongest acid of the following HOCl Hoi HOBr?
Justify your answer in terms of Ka . HOCl is the stronger acid because its Ka value is greater than the Ka value of HOBr.
Is HOBr stronger than Hoi?
HOCl is a stronger acid than HOI because the Cl is far more electronegative than the I in their respective acids. The more electronegative a molecule is, the less electron density around the H, making it easier for the H to be donated to another molecule.
Which is more acidic HOCl or 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 represents correct order of acidic strength HOCl HOBr Hoi?
Thus the acidic strength follows the order: HClO4>HBrO4>HIO4.
Why is HOBr stronger than HOCl?
In Group 17 oxyacids, electron density is drawn away from the O atom as the electronegativity of the halogen increases. This in turn draws electron density away from the O–H bond and weakens it. The weaker the O–H bond, the stronger the acid. Cl is more electronegative than Br so HOCl is stronger acid than HOBr.
Is HOBr weak acid?
Hypobromous acid, HOBr , is a weak acid that dissociates in water, as represented by the equation above. (a) Calculate the value of [H+] in an HOBr solution that has a pH of 4.95.
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.
Why HOF is stronger acid than HOCl?
As the O−H bond length decreases, the acidic nature of the compound increases. In HOF , the O−H bond length is 96 pm while in HOCl, the O−H bond length is 97 pm and so HOF is more acidic than HOCl.
Which of the following is strongest acid HOCl?
HCIO4orHOCl3 ( C) is the strongest acid acid.
Why is HOBr weaker than HOCl?
Why Ho Hoi is a strong acid?
HoI is the strong acid because the acidic nature of the acid depends on the electronegativity of the atom. And down the group the electronegativity decreases. As electronegativity decreases the acidic nature of the acid increase. In this the the electronegativity is in the order given is ofluorine >chlorine >bromine >iodine.
Why is H OC l a stronger acid than H OBR?
The weaker the O−H bond, the stronger the acid. Chlorine is more electronegative than Bromine which reduces the strength of O− H bond in H OC l. Thus H OC l is stronger acid than H OBr. Was this answer helpful?
Why is HCl the strongest acid in nature?
HCl and the rest of them (HBr, HI) are all “strong acids” but HI is the strongest (see pKa’s below) Due to poor orbital overlap (Iodine is much larger than H, and therefore the electrons are not very well shared, which imparts an extremely ionic character to the molecule)
What does the Order of acid strength of halogen compounds indicate?
It means more the electronegativity of the halogen atom, more the tendency to pull electron and weaker the O-H bond and hence proton (H+) can easily remove. Example: HOF is strongest acid, HOI is weakest acid (order of acid strength is HOF > HOCl > HOBr > HOI)
