Question

Select the incorrect statement about the boron.

Options

A.Pure form of the elements are obtained by the reduction of BCl₃ with zinc at 900^oC.

B.Crystalline boron is attacked only by hot concentrated oxidising agents.

C.Amorphous boron and ammonia at white heat gives (BN)_x, a slippery white solid with a layer structure resembling that of graphite.

D.Boron does form B³⁺ cation easily.

Due to small size of boron, the sum of its first three ionization enthalpies is very high. This prevents it to form +3 ions.
