Question

which will exist as individual molecules? select all correct options nacl f2 co2 cacl2

Explanation:

Step1: Identify ionic or covalent compounds

Ionic compounds form crystal - lattices, not individual molecules. Covalent compounds can exist as individual molecules.

Step2: Analyze NaCl

NaCl is an ionic compound formed by the transfer of electrons from Na to Cl. It exists as a three - dimensional ionic lattice.

Step3: Analyze F₂

F₂ is a covalent compound, a diatomic molecule held together by a covalent bond. It exists as individual molecules.

Step4: Analyze CO₂

CO₂ is a covalent compound with covalent bonds between C and O. It exists as individual molecules.

Step5: Analyze CaCl₂

CaCl₂ is an ionic compound formed by the transfer of electrons from Ca to Cl. It exists as a three - dimensional ionic lattice.

Answer:

B. F₂, C. CO₂
