question\nidentify the compound containing polar covalent bonds.\nselect the correct answer below:\n○ f₂\n○ ccl₄\n○ n₂\n○ h₂
Answer
Answer:
B. $\mathrm{CCl}_{4}$
Explanation:
Step1: Recall polar - covalent bond concept
Polar covalent bonds occur between atoms with different electronegativities.
Step2: Analyze $\mathrm{F}_{2}$
In $\mathrm{F}_{2}$, both atoms are fluorine. Same - element bond, electronegativity difference is 0, non - polar bond.
Step3: Analyze $\mathrm{CCl}_{4}$
Carbon and chlorine have different electronegativities. $\mathrm{C}-\mathrm{Cl}$ bonds are polar covalent.
Step4: Analyze $\mathrm{N}_{2}$
In $\mathrm{N}_{2}$, both atoms are nitrogen. Same - element bond, electronegativity difference is 0, non - polar bond.
Step5: Analyze $\mathrm{H}_{2}$
In $\mathrm{H}_{2}$, both atoms are hydrogen. Same - element bond, electronegativity difference is 0, non - polar bond.
