Chemistry - Complete Pblock- Question with Solution | TestHub

Combustion & Hydrolysis: Reactions (A) and (B) are correct as diborane reacts exothermically with O₂ to form B₂O₃ and reacts with water to produce H₃BO₃ and H₂ gas.

Symmetrical Cleavage: Reaction (D) is correct because CO and bulky amines like NMe₃ cause symmetrical cleavage of the B₂H₆ bridge, yielding simple adducts ($B{H}_3\cdot L$).

Unsymmetrical Cleavage: Reaction (C) is incorrect because NMe₃ is too bulky for unsymmetrical cleavage; that specific ionic product is typically formed with smaller bases like NH₃.
