Question

Does boron halides undergo hydrolysis?

Akanksha C. · Accepted Answer

Hi,

Except BF3 all other boron halides undergo hydrolysis to
give orthoboric acid The reaction of hydrolysis of BCl3
is given below :

BCl3(g) + 3Hâ€‹2O(l)
-----> B(OH)3 (aq) + 3HCl (aq)

BF3 does not undergo hydrolysis due to strong B-F bond
in BF3 molecule
