Which of the following molecules contains a polar covalent bond? A) H₂ B) F₂ C) CH₃Cl D) NaCl E) He

Question

Quizplus · Accepted Answer

A polar covalent bond is formed when two different atoms share a pair of electrons unequally, creating partially positive and partially negative ends of the molecule. In option C, there is a polar covalent bond between carbon and chlorine, as chlorine is more electronegative than carbon and attracts the bonding electrons towards itself, creating a partial negative charge on chlorine and a partial positive charge on carbon. The other options do not have polar covalent bonds. Option A and B do not have any atoms with significantly different electronegativities, and option D has an ionic bond between sodium and chlorine. Option E is a noble gas and does not form covalent bonds with other atoms.
