Comparison of acidic strength between nitric acid and nitrous acid. 3. Why is hydrobromic acid a stronger acid than hypobromous acid? 2. SpletWhy is BF3 a weaker Lewis acid than BCl3 and bbr3? It takes more energy to lengthen the short, strong B-F bonds than the longer, weaker B-Cl bonds. Hence BF3 is a weaker Lewis acid than BCl3 .

Splet11. apr. 2024 · Answer: BCl3 is the stronger Lewis acid because the Boron center in BF3 participates in 2p (pi)-2p (pi) back bonding with the Fluorine atoms with a greater overlap thereby reducing it’s deficiency. Is fe2+ or fe3+ a stronger Lewis acid? Therefore the stronger Lewis acid among the given is Fe3+. Which is a stronger Lewis acid BCl3 or BBr3? Splet24. jan. 2024 · But, in the case of AlCl3, the size of Al is large so incoming electrons are less attracted. (Since Boron is more electronegative than Aluminium, it can attract electrons more easily and since Lewis acids are electron acceptors, BF3 is a stronger Lewis acid than AlCl3). Thus BF3 is better Lewis acid than AlCl3. Share Improve this answer Follow
