How can the following reaction be made to proceed in forward direction ?
`B(OH)_(3) + NaOH hArr Na[B(OH)_(4)]`.

A

Addition of cis 1,2 diol

B

addition of borax

C

addition of trans 1,2 diol

D

addition of `Na_(2)HPO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
`B_(3)BO_(3)` acts are weak monobasic Lewis acid.
(i) `B(OH)_(3)+NaOH to Na[B(OH)_(4)]`
On addition of cis 1,2 diol in `H_(3)BO_(3)` solution, acidic strength of `H_(30BO_(3)` increases due to chelation effect.
