Draw the structure of boric acid showing hydrogen bonding. Which species is present in water ? What is the hybridizations of boron in this species ? |
|
Answer» Solution :It has a layer structure in which planar `H_3BO_3` units are JOINED by HYDROGEN bonds forming hexagonal rings. Boric ACID is a weak monobasic acid. It is not a protonic acid but acts as a LEWIS acid by accepting electrons from a hydroxyl ion. In water, boric acid is present in the form of `[B(OH)_4]^(-)`species. The HYBRIDIZATIONS of boron in this species is `sp^3`. `B(OH)_3+ 2HOH to [B(OH)_4]^(-) + H_3O^+`
