The correct statement(s) for orthoboric acid is/are

1.	The correct statement(s) for orthoboric acid is/are
Answer» it behaves as a weak acid in water due to self ionization acidity of its aqueous solution increases upon addition of ethylene GLYCOL it has a three-dimensional structure due to hydrogen bonding it isa weak electrolyte in water Solution :Orthoboric ACIDIS a weak monobasic Lewis acid. It acceptsa pair of electronsfrom `OH^(-)`ion of `H_(2)O` releasinga proton. On adding ethylene glycol, it acidity increases `H_(3)BO_(3)`, however, does notundergo self ionization to releasea proton. Further due to H-bonding , `H_(3)PO_(3)` is a planarmolecule .Thus only OPTION (b,d) correct.
