Hydrogen bonding plays a central role in the following phenomena:a)Ice...
(A) Ice has cage-like structure in which each water molecule is surrounded by four other water molecules tetrahedrally through hydrogen boding, due to this density of ice is less than water and it floats in
water.
water.
The cation (I) more stabilized through hydrogen boding than cation (II) . So, R–NH2 is better base than (R)3N in aqueous solution.
(C) HCOOH is stronger acid than CH3COOH due to inductive effect and not due to hydrogen bonding.
(D) Acetic acid dimerizes in benzene through intermolecular hydrogen bonding.

Ice floats in water:
Hydrogen bonding between water molecules causes them to arrange themselves in a hexagonal lattice structure in the solid form (ice). This arrangement creates empty spaces between the molecules, making ice less dense than liquid water and causing it to float.
Higher Lewis basicity of primary amines than tertiary amines in aqueous solutions:
Primary amines have a hydrogen atom directly bonded to the nitrogen atom, allowing them to form stronger hydrogen bonds with water molecules compared to tertiary amines. This stronger interaction results in primary amines exhibiting higher Lewis basicity in aqueous solutions.
Dimerisation of acetic acid in benzene:
In non-polar solvents like benzene, hydrogen bonding is not as significant as in polar solvents. However, acetic acid can still undergo dimerization in benzene due to the formation of intermolecular hydrogen bonds between the carbonyl oxygen of one molecule and the hydrogen of the hydroxyl group of another molecule. This dimerization is facilitated by the presence of hydrogen bonding interactions.
