Question

question 3 of 10 which of the following molecules contains a nonpolar covalent bond? a h₂ b h₂o c hcl d lii

Explanation:

A polar covalent bond occurs when there is an unequal sharing of electrons between atoms due to differences in electronegativity. In $H_2$, the two hydrogen atoms have the same electronegativity and share electrons equally, so it has a non - polar covalent bond. In $H_2O$, oxygen is more electronegative than hydrogen, leading to unequal electron sharing and polar covalent bonds. In $HCl$, chlorine is more electronegative than hydrogen, resulting in a polar covalent bond. In $LiI$, it is an ionic compound formed by the transfer of electrons from lithium to iodine.

Answer:

B. $H_2O$, C. $HCl$
