Which reaction occurs when hydrofluoric acid dissolves glass?

A)Covalent bond disruption of silicon dioxide
B)Hydrogen bond destruction between silanols
C)Electrostatic attraction increases for dissolved ions
D)Metallic bonding weakens silicate network energies

💡 Explanation

Glass etching occurs because hydrofluoric acid induces nucleophilic attack affecting the covalent bonds in SiO₂, resulting in the formation of hexafluorosilicates via chemical transformations. Therefore, the covalent bonds are disrupted rather than hydrogen bonds since HF directly reacts with the silica itself.
