Class XI The p-Block Elements Page 325

Answer 1

The attractive electrostatic force between a Hydrogen atom ( which is already covalently attached to a strong electronegative atom e.g, any of F, O and N ) and and electronegative atom(any out if F , O and N) is known as Hydrogen bond.according to explanation of H-bond it is clear that in boric acid H-bond exists. Due to structure of boric acid like layer and polymeric .
Hence, Boric acid is polymeric due to the presence of Hydrogen bond.Hence, option (b) is correct
