Which of the following hydrocarbons has thehighest melting point?a)o-Xyleneb)p-Xylenec)m-Xylened)TolueneCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Melthing point order p>o>m on basis of symmetry soo option b is ryt..

Answer

Since it is in para position it can easily form hydrogen bond with neighbor molecule.Therefore it is difficult to melts the p-xylene than others

Answer

Explanation:

- p-Xylene has the highest melting point among the given options.

- The melting point of a compound is influenced by its molecular structure and intermolecular forces.

- In the case of Xylenes and Toluene, these are isomeric hydrocarbons with similar molecular weights but different structures.

- Among o-Xylene, m-Xylene, and p-Xylene, p-Xylene has a symmetrical structure which allows for stronger intermolecular forces such as van der Waals forces compared to the other isomers.

- These stronger intermolecular forces result in a higher melting point for p-Xylene compared to the other isomers.

- Toluene, on the other hand, has a lower melting point compared to Xylenes due to its simpler molecular structure and weaker intermolecular forces.

Therefore, p-Xylene has the highest melting point among the given hydrocarbons.

Answer

Any other rule

Answer

Melting point order is para > ortho > meta on basis of symmetry . So option b is correct.
