Expalin the following observations:
a. Benzene is soluble in water whiel both `1,3-` and `1,4-` cyclohexadiene are insouble.
b. Melting point of benzene `(32K)` is much higher than both `1,3-` and `1,4-` cyhexadiences.
c. `P-` Xylene has higher metling point than `o-` and `m-` xylenes.

Verified by Experts

a. The delocalised `6pi oveline(e)'s` in benzene are more easily polarised resulting in greater van der Walls attractive forces to `H_(2)O` hence more soulle.
b. Benzene can be packed symmetrically in its crystal latice because benzene is a plannar moleucule.
b. Benzene can be packed symmetrically in its crystal latice because benzene is a planar moleucule.
c. `p-` Xylene has a symmetrical structure and can fit better into the crystal lattice than the `o-` or `m-` isomers.
