Question

Which one has a higher boiling point o-chlorobenzene or p-dichlorobenzene?

Answer 1

ANSWER:-

➡P-Dichlorobenzene has higher boiling point than O-chlorobenzene.

EXPLANATION:-

➡Due to symmetrical structure of Para dichlorobenzene there exist strong intermolecular forces than Ortho chlorobenzene. It requires high energy for P-Dichlorobenzene to break these bonds during boiling.

Therefore p-Dichlorobenzene has higher boiling point.
