Question

p-dichlorobenzene has a higher melting point than its o- and m-isomers because ____________.

Options

• p-dichlorobenzene is more polar than o- and m-isomer

• p-isomer has a symmetrical crystalline structure

• boiling point of p-isomer is more than o- and m-isomer

• All of these are correct reasons

Answer 1

p-dichlorobenzene has a higher melting point than its o- and m-isomers because p-isomer has a symmetrical crystalline structure.
