para - isomers have high melting point as compared to ortho and meta-isomers. Explain.

Text Solution

Verified by Experts

Due to more symmetrical arrangement, para isomers can fit more tightly into crystal lattice. Bus ortho and meta isomers have non symmetrical arrangement and form unoccupied space. Therefor para isomers have high melting point as compared to ortho and meta isomers.
