Question

Which of the following compound is non-polar?

• A. $CC{l}_4$
• B. $C{H}_{2}C{l}_2$
• C. $CHC{l}_3$
• D. $C{H}_{3}Cl$

Answer 1

The correct option is A $CC{l}_4$

Therefore the resultant ${\mu }_{net}=0$ dipole moment obtained from the down $Cl$ cancels the effect of the dipole moment of the above $Cl$. Thus dipole moment is equal to zero. Thus, Non-polar.

Due to unsymmetrical dipole moment exits in rest of the molecules. Hence, they are polar.
