Explain why: (i) is a Lewis acid. (ii) Boric acid is a monobasic acid. |

Answer» mpound "ACCEPTS" a electrons pair from donor called Lewis acid. Due to electron deficient nature of , it accepts a electrons from "electron rich" species compound LIKE ammonia. The central atom of boron trichloride is boron as it is an electron deficient and it accepts a "electrons pairs" and ACT as Lewis acid. ii) "BORIC acid" is often referred to as orthoboric acid. Although, Boric acid contains three OH groups, it can still act as a monobasic acid instead of a tri-basic acid. "Boric acid" does not act as a protons donor, but rather accepts a "lone pair" of electrons from "OH ions". THEREFORE, it can be act as monobasic Lewis acid. |
