One of the hydrolysed product of the following compound does not react with silica of glass vessel

Options

  1. AB F 3
  2. BC l F 5
  3. CX e F 2
  4. DS F 4

Correct answer

A. B F 3

Step-by-step solution

In case of hydrolysis of B F 3 , HF is not formed so no reaction with Silica glass vessel. 4 B F 3 + 3 H 2 O → Room Temperature H 3 B O 3 + 3 H [ B F 4 ] ⏟ doesnotreact withsilica ( Si O 2 )
