Question

which of the following do you think would melt first, nacl (ionic bond) or c6h12o6 (covalent bond)?
nacl
c6h12o6

Explanation:

Ionic compounds (like NaCl) have strong electrostatic forces between ions, leading to high melting points. Covalent compounds (like C₆H₁₂O₆) have weaker intermolecular forces (e.g., van der Waals forces, hydrogen bonds depending on the compound). Weaker forces mean less energy is required to break them, so covalent compounds generally melt at lower temperatures than ionic ones.

Answer:

C₆H₁₂O₆
