Why para-dichlorobenzene has more melting point?
Thus para-dichlorobenzene has a closed packed crystal structure. So more energy is needed to break the crystal lattice of para-dichlorobenzene than ortho and meta isomers. Due to this reason, para-dichlorobenzene has higher solubility and a higher melting point than ortho and meta- isomer.
Why is the melting point of p-Dichlorobenzene higher than that of O and M isomers?
p-Dichlorobenzene has higher melting point and solubility than those of o- and m-isomer. The melting point of p-isomer is quite higher than ortho and meta isomers. This is due to the fact that it has symmetrical structure and therefore its molecules can be easily packed closely in crystal lattice.

Which Dichlorobenzene has highest melting point?
p-Dichlorobenzene
p-Dichlorobenzene fits closely in the crystal lattice due to its symmetrical structure. Therefore, it has highest melting point.
Why is melting point of p-dichlorobenzene higher than o-dichlorobenzene But boiling point of o isomer is higher than P isomer?
p-Dichlorobenzene is more symmetrical than o-and m-isomers. For this reason, it fits more closely than o-and m-isomers in the crystal lattice. Therefore, more energy is required to break the crystal lattice of p-dichlorobenzene. As a result, p-dichlorobenzene has a higher melting point than o-and m-isomers.
Which dichlorobenzene has highest melting point?
Is paradichlorobenzene flammable?
Flammable Properties Not flammable.
Is paradichlorobenzene soluble in water?
CHEMICAL AND PHYSICAL PROPERTIES Pure Paradichlorobenzene is a colorless to white crystal solid that evaporates continuously even at room temperature. It is practically insoluble in water but will dissolve readily in alcohols and other organic solvents.
Which is the melting point of paradichlorobenzene?
The structure of Paradichlorobenzene is C6H4Cl2. What is the melting point of Paradichlorobenzene? It is 53.1 degrees C. now, here the question arises, why the melting point of Paradichlorobenzene is higher in comparison to O dichlorobenzene.
What can paradichlorobenzene be used for?
Paradichlorobenzene is a synthetic, white crystalline solid that is practically insoluble in water and soluble in ether, chloroform, carbon disulfide, benzene, alcohol and acetone. It is used primarily as a space deodorant in products such as room deodorizers, urinal and toilet bowl blocks, and as an insecticide fumigant for moth control.
What are the physical properties of para dichlorobenzene?
The physical properties of Para Dichlorobenzene are: 1 Mothball-lie odour 2 White liquid appearance 3 Water solubility: 0.08g/L (80 mg/L) at 25 degree C 4 Vapour pressure: 1.3 mmHg 5 Gravity: 1.24 g/mL
Why does paradichlorobenzene fit in any crystal lattice?
The answer to this question is because Paradichlorobenzene happens to be more symmetrical in comparison to m and o isomers; hence it fits closely in any crystal lattice than is the case with m and o isomers. It is only because of this reason that extra energy is needed for breaking Paradichlorobenzene crystal lattice.
