Answer
Explanation:
Step1: Analyze bonding in CF₄
CF₄ is a molecular - covalent compound. The atoms of C and F are held together by covalent bonds. The intermolecular forces are London - dispersion forces.
Step2: Analyze bonding in CCl₄
CCl₄ is also a molecular - covalent compound. It has covalent bonds between C and Cl atoms and London - dispersion forces as intermolecular forces.
Step3: Analyze bonding in CO₂
CO₂ is a molecular - covalent compound. It has covalent bonds between C and O atoms and London - dispersion forces (weak intermolecular forces) as the main intermolecular attraction.
Step4: Analyze bonding in BaO
BaO is an ionic compound. It is formed by the transfer of electrons from Ba (a metal) to O (a non - metal), resulting in the formation of Ba²⁺ and O²⁻ ions. The ionic bonds between these ions are much stronger than the intermolecular forces in molecular compounds.
Step5: Compare melting points
Ionic compounds generally have higher melting points than molecular compounds due to the strong electrostatic forces (ionic bonds) between ions compared to the weak intermolecular forces (London - dispersion forces) in molecular compounds.
Answer:
| Substance | Bonding | Highest Melting Point |
|---|---|---|
| CF₄ | Covalent (Molecular) | |
| CCl₄ | Covalent (Molecular) | |
| CO₂ | Covalent (Molecular) | |
| BaO | Ionic | $\checkmark$ |
