All the boron trihalides except `BI_(3)` may be prepared by direction between the elements. Boron trihalides consist of trigonal-planar `BX_(3)` molecules. Unlike the halides of the other elements in the group they are monomeric in the gas, liquid and solid states, `BF_(3)` and `BCl_(3)` are gases, `BBr_(3)` is a volatile liquid and `BI_(3)` is a solid. Boron trihalides are Lewis acids because they form simple Lewis complexes with suitable bases, as in the reaction: `BF_(3)(g)+NH_(3)(g)toF_(3)B-NH_(3)(s)` However, boron chlorides, bromides and iodides are susceptible (sensitive) to protolysis by mild proton sources such as water, alcohols and even amines, for example `BCl_(3)` undergoes rapid hydrolysis: `BCl_(3)(g)+3H_(2)O(l)toB(OH)_(3)(aq)+3HCl (aq)` It is supposed that the first step in the above reaction is the formation of the complex `Cl_(3)B larr OH_(2)` which then eliminates `HCl` and reacts with water. Which is correct about the hydrolysis of `BX_(3)`?A. All `BX_(3)` undergo hydrolysis to produce `B(OH)_(3) (aq)` and `HX(aq)`.B. `BF_(3)` does not undergo complete hydrolysis due to formation of `HBF_(4)`C. `BBr_(3)` does not undergo hydrolysis at all because it cannot form `H`-bonds with water.D. All the above are correct
