Solution

The correct option is A $H_{2} {B O}_{3}$ dissolve in water
Correct Option $- A$
Reason:-
$H_{3} B O_{3} ⟶ H B O_{2} + H_{2} O$
$H_{3} B O_{3}$ has $s p^{3}$ hybridisation at the central atom and $H B O_{2}$ has $s p^{2}$ hybridisation at the central atom.

Out of given reaction which show change in hybridization of central atom__________.

The correct option is A H2BO3 dissolve in waterCorrect Option −AReason:- H3BO3⟶HBO2+H2OH3BO3 has sp3 hybridisation at the central atom and HBO2 has sp2 hybridisation at the central atom.

The correct option is A $H_{2} {B O}_{3}$ dissolve in water
Correct Option $- A$
Reason:-
$H_{3} B O_{3} ⟶ H B O_{2} + H_{2} O$
$H_{3} B O_{3}$ has $s p^{3}$ hybridisation at the central atom and $H B O_{2}$ has $s p^{2}$ hybridisation at the central atom.
