Question

Which compound is a non-polar, molecular substance?

• A. $Ba{Cl}_2$
• B. ${CH}_{3}Cl$
• C. $B{I}_3$
• D. $H_{2}O$

Answer 1

Answer: (C)

$B{I}_3$

$BaC{l}_2$ is neither polar nor non polar. It is ionic.

$C{H}_{3}Cl$ and $H_{2}O$ has a non zero dipole moment due to which they are polar.

$B{I}_3$ having symmetrical sharing of valence electrons whose resultant dipole moment is zero, hence is a non polar molecule.
