Boric acid in solid, whereas BF3{BF}_{3} is gas at room temperature because ofBoric acid in solid, whereas BF _ 3 is gas at room temperature because of

Options

  1. AStrong ionic bond in Boric acid
  2. BStrong van der Waal's interaction in Boric acid
  3. CStrong hydrogen bond in Boric acid
  4. DStrong covalent bond in BF3{BF}_{3}

Correct answer

C. Strong hydrogen bond in Boric acid

Step-by-step solution

Inter-molecular structure of Boric acid(H3BO3{H}_{3}{BO}_{3}) in solid phase:
Boric acid in solid, whereas BF _ 3 is gas at room temperature because of
Boric acid has strong hydrogen bonding as we can see in the above figure, while BF3{BF}_{3} does not. Therefore boric acid is solid.
