SURVEY . Bromous acid is the inorganic compound with the formula of HBrO 2.It is an unstable compound, although salts of its conjugate base – bromites – have been isolated. Question =  Is SCN- polar or  nonpolar ? For the conjugate base to get stabilisation, the weak $\ce{-I}$ effect of $\ce{Br}$ atom is not at all sufficient. 20 seconds . Does the hero have to defeat the villain themselves? Expert Answer . Instead, if the lone pairs can somehow delocalise that will contribute better to stability of the conjugate base. Tags: Question 3 . The HO bond in HBrO is more polar than the HO bond in HBrO3 C. The HBr bond in HBro is weaker than the HBr in HBrO3 D. Durable sneakers will save a single shoe repair expenses. HBrO. More over if you dissolve it in a sloution, the weak bond is easily broken, and the individual cations and anions can get extensively solvated which makes the whole process of dissociation thermodynamically very much favourable.That's why, the $\ce{pK_a}$ of $\ce{HBr}$ is very low which means it can dissociate very easily in a solvent. Why does a proton prefer to attack a double bond instead of protonating an alcohol in a reaction of unsaturated alcohol with sulphuric acid? The more polar the O–H bond, the more readily it is broken and the stronger the acid. This makes calculating the hydrogen ion concentration, which is the basis of pH, easier than for weak acids. If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. Make integer sequence unique at compile time. It only takes a minute to sign up. Since chlorine is more electronegative than bromine, HClO4 is a stronger acid than HBrO4. The structure of $\ce{HBr}$ and $\ce{HBrO}$ is different, and also the place from where the proton leaves the molecule is also diferent.So, we have to take account of this and also the stability of the conjugate base formed after deprotonation.In $\ce{HBrO, }$ the proton is attached to the $\ce{O}$ atom of the molecule.The molecule can lose proton as, $$\ce{H -O -Br <=> H^+ + (O -Br)^-}$$ The negative charge here mainly resides on the Oxygen, which makes $3$ lone pairs on $\ce{O}$ atom, adjacent to that, there is also electron rich $\ce{Br}$ atom, which also has $3$ lone pairs on it, so there are inter electronic repulsions. Under what circumstances can a bank transfer be reversed? A. Because it easily gives up its hydrogen atom in the form of a H+ ion. Help to find the right tyre for my Scott ebike. Can you know the damage before teleporting with Cleric Peace Domain Lvl6 Protective Bond? In aqueous solution, classify these compounds as strong acids, weak acids, strong bases, weak bases, or other. Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). HBrO is a little stronger than HIO because Br is stronger in electronegativity than I. HClO is a little stronger than HBrO because Cl is stronger in electronegativity than Br. Indicate which is the stronger acid: (a) HBrO 3 or HBrO 4; (b) H 2 SeO 4 or H 2 SO 4. In acidic solution, bromites decompose to bromine. Question =  Is CLO3- polar or  nonpolar  ? Some weak acids: HF, HNO 2, HClO 2, [H 2 SO 3] = SO 2 + H 2 O, HC 2 H 3 O 2 = HOAc 2. HBr is a strong acid because the overlap of orbitals between H and Br atom is small due to the different orbital size, 1s and 4p orbitals, hence the bond strength of H-Br is weak and is easily broken. And how do we decide which factor weighs more? Question =  Is ClF polar or  nonpolar ? Answer =  CF2Cl2  (Dichlorodifluoromethane)  is  Polar What is polar and non-polar? It is about the strength of the H-Br versus H-I bond. If one tomato was moulded, is the rest of the pack safe to eat? A strong acid is one that completely dissociates into its ions in water. Why is the House of Lords considered a component of modern democracy? HNO3. H3PO4. Why doesn't China allow American social media companies to operate in China? all acids and bases are strong. The HO bond in HBrO is less polar than the HO bond in HBrO3 B. If my understanding is correct, bromous acid ( H B r O X 2) is a stronger acid than hypobromous acid ( H B r O) because the additional electronegative oxygen atom draws the electron away from the hydrogen atom, making dissociation for H X + easier. So, due to high electronic repulsion, no chances of delocalisation, and very weak $-I$ effect of $\ce{Br}$ can't make the conjugate base stable at all. Like the acid, hypobromite salts are unstable and undergo a slow disproportionation reaction to yield the respective bromate and bromide salts.. 3 BrO − (aq) → 2 Br − (aq) + BrO − 3 (aq). This problem has been solved! So after they spill, it is really extremely important to incorporate them right absent to reduce their distribute.
