P-Block Elements Ques 527

Question: $B {(O H)}_{3} + N a O H \to N a B O_{2} + N a [B {(O H)}_{4} + H_{2} O$ How can this reaction is made to proceed in forward direction?

Options:

A) addition of cis 1,2-diol

B) addition of borax

C) addition of trans 1,2-diol

D) addition of $N a_{2} H P O_{4}$

Show Answer

Answer:

Correct Answer: A

Solution:

$H_{3} B O_{3}$ acts as weak monobasic Lewis acid. $B {(O H)}_{3} + N a O H \to N a [B {(O H)}_{4}]$ 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.
