Question

1. which molecule is nonpolar due to equal sharing of electrons?

a. oxygen (o₂)
b. ethanol (c₂h₅oh)
c. ammonia (nh₃)
d. water (h₂o)

Explanation:

In oxygen ($O_2$), two oxygen atoms have the same electronegativity, so electrons are shared equally between them, making it non - polar. Ethanol ($C_2H_5OH$), ammonia ($NH_3$) and water ($H_2O$) have polar bonds due to differences in electronegativity between their constituent atoms.

Answer:

a. Oxygen ($O_2$)
