How would replacing one of the hydrogen atoms in CH₄ with a chlorine atom affect the molecule's polarity?

• A. The molecule would become nonpolar because chlorine is less electronegative than hydrogen.
• B. The molecule would remain nonpolar because the shape is still perfect.
• C. The molecule would become polar due to the difference in electronegativity between hydrogen and chlorine.
• D. The molecule would become ionic due to the presence of chlorine.

Answer: (C)
