Boric acid is used in carrom boards for smooth gliding of pawns because
1 \(\mathrm{H}_{3} \mathrm{BO}_{3}\) molecules are loosely chemically bonded and hence soft
2 its low density makes it fluffy
3 it is chemically inert with the plywood
4 \(\mathrm{H}\) - bonding in \(\mathrm{H}_{3} \mathrm{BO}_{3}\) gives it a layered structure
