← ScienceWhich mechanism influences the melting point of ice due to hydrogen bonding?
A)Tetrahedral network stabilization✓
B)Van der Waals forces enhancement
C)Dipole-dipole interaction amplification
D)Covalent bond length reduction
💡 Explanation
When ice forms, hydrogen bonds create a tetrahedral network because each water molecule donates and accepts two hydrogen bonds, stabilizing the structure and requiring more energy to disrupt during melting. Therefore network stabilization elevates the melting point, rather than van der Waals forces, dipole interactions or bond contractions that are comparatively weaker or absent.
