Boric acid is used in carrom boards for smooth gliding of pawns because:
A.H₃BO₃ molecules are loosely chemically bonded and✓ Correct
B.its low density makes it fluffy
C.it is chemically inert with the plywood
D.H-bonding in H₃BO₃ gives it a layered structure
Explanation
Boric acid acts as a solid lubricant. It is used to reduce friction on the surface of carrom board. It makes the motion smoother. 3 3 H BO Boric Acid molecules are loosely chemically bonded and hence it is soft which helps to reduce friction.
