Question

B ( O H ) 3 + N a O H → N a B O 2 + N a [ B ( O H ) 4 ] + H 2 O How can this reaction is made to proceed in forward direction?, addition of cis 1,2 diol, addition of borax, addition of trans 1,2 diol, addition of N a 2 H P O 4

MARKS App · Accepted Answer

H 3 B O 3 acts as a weak monobasic Lewis acid B ( O H ) 3 + N a O H → N a [ B ( O H ) 4 ] On addition of cis 1, 2 diol in H 3 B O 3 solution, acidic strength of H 3 B O 3 increases due to chelation effect.
