Water has a high boiling point because of the presence of extensive hydrogen bonding interactions between the water molecules in the liquid phase (water is both a strong hydrogen bond donor and acceptor). When heat is first applied to water, it must break the intermolecular hydrogen bonds within the sample.

Explanation:
Water molecules are held together by hydrogen bonds, which are relatively strong intermolecular forces. Due to this, water has unique properties such as high boiling and melting points.
High Freezing Point:
The extensive hydrogen bonding between water molecules causes them to arrange themselves in a highly ordered structure when they freeze. This ordered structure takes up more space than the disordered liquid, which is why ice is less dense than liquid water. As a result, ice floats on water. The extensive hydrogen bonding between water molecules also makes it difficult to break the bonds and melt the ice. This is why water has a high freezing point.
High Boiling Point:
Similarly, the extensive hydrogen bonding between water molecules makes it difficult to break the bonds and turn the liquid into vapor. This is why water has a high boiling point.
Therefore, the presence of extensive hydrogen bonding between water molecules leads to a high freezing point and a high boiling point.
