Answer
Explanation:
Step1: Analyze bonding in NF₃
NF₃ is a molecular - covalent compound. The atoms N and F are non - metals and they share electrons to form covalent bonds.
Step2: Analyze bonding in CO₂
CO₂ is also a molecular - covalent compound. Carbon and oxygen are non - metals and form covalent bonds by sharing electrons.
Step3: Analyze bonding in O₂
O₂ is a diatomic molecular - covalent substance. Two oxygen atoms share electrons to form a covalent bond.
Step4: Analyze bonding in NaBr
NaBr is an ionic compound. Sodium (a metal) donates an electron to bromine (a non - metal) to form an ionic bond.
Step5: Compare melting points
Ionic compounds generally have higher melting points than molecular - covalent compounds due to the strong electrostatic forces between ions in the ionic lattice compared to the relatively weak intermolecular forces (such as London dispersion forces, dipole - dipole forces) in molecular compounds.
Answer:
| Substance | Bonding | Highest Melting Point |
|---|---|---|
| NF₃ | Covalent | |
| CO₂ | Covalent | |
| O₂ | Covalent | |
| NaBr | Ionic | X |
