Which substance has nonpolar covalent bonds?
Answer and Explanation: Covalent bonds are formed between two or more nonmetals (nonmetals are located on the left side of the staircase on the Periodic Table). Looking at the answer choices, we can see that all of the answers have nonmetals, and therefore all have covalent bonds.
The molecule that is composed of the same two elements has non polar covalent bonds since same elements have the same electronegativities and share electrons in the bond equally.
Looking at the answer choices, we can see that choice (1) Cl2 is the right answer since the molecule is composed of two same elements, chlorines.
