Question

Which one of the following is a non-polar molecule ?

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

Answer 1

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

A compound that has a net dipole moment is zero are non-polar compounds. $CC{l}_4$ has a perfect tetrahedral shape, where the 4 $C-Cl$ bonds are along the edge of a tetrahedron. The resultant bond moment of 3 $C-Cl$ bond gets canceled out by the fourth bond. The net dipole moment of the bond is zero.

Option A is correct.
