    In BF3​ molecule, B−F bond has partial double bond due to presence of pπ−pπ backbonding between B and F, which removes the electron deficienty of the molecule. Due to this, B−F bond length is reduced to 130 pm. When BF3​ changes to BF4−​, the hybridization changes from sp2 to sp3. The double bond character changes to single bond and the B−F bond length becomes 143 pm.

    yes, BF3, BCl3 and BH3 can undergo hydrolysis. Unlike other boron halides, BF3 does not hydrolyse completely. Instead, it hydrolyses incompletely to form boric acid and fluoroboric acid. This is because the HF first formed reacts with H3BO3.
