Question

question 8 (1 point) listen which of the molecules is polar? a) f₂ b) h₂o c) h₂ d) kcl e) o₂

Explanation:

A polar molecule has a net dipole moment due to unequal sharing of electrons. In $F_2$, $H_2$ and $O_2$, the atoms are identical, so the electron - sharing is equal and they are non - polar. $KCl$ is an ionic compound, not a covalent molecule in the traditional sense for this context. Water ($H_2O$) has a bent molecular geometry and the oxygen atom is more electronegative than hydrogen, creating a net dipole moment and making it polar.

Answer:

B. $H_2O$
