Question

a lewis structure for the molecule 1,4 - dichlorobenzene (c6h4cl2) is shown. based on this structure, determine if the molecule is polar or nonpolar.

Explanation:

The molecule \(C_6H_4Cl_2\) (1,4 - dichlorobenzene) has a symmetrical structure. In a symmetrical molecule, the dipole moments of the \(C - Cl\) bonds (which are polar due to the electronegativity difference between \(C\) and \(Cl\)) cancel each other out. For 1,4 - dichlorobenzene, the two \(C - Cl\) bonds are opposite each other on the benzene ring. The vector sum of their dipole moments is zero.

Answer:

Nonpolar
