Q.--haloalkanes

1) Out of C₆H₅CH₂Cl and C₆H₅CHClC₆H₅
which is more easily hydrolysed by aqueous KOH. (please explain whether it is SN1 or SN2 for each)

2) p-dichlrobenzene has higher or lower solubility than those of o- and m- isomers ?

For 1st one, the former compound is hydrolyzed by SN2 while the latter is by SN1.

2) lower solubility due to zero dipole moment.

Is there any role of melting point in deciding solubility in 2nd question ?

How to decide whether 2Â° alkyl halide uses SN1 or SN2 mechanism if type of solvent is not given ?

In general, Solvation is a solvent phenomenon and is mostly by SN1 mechanism. If nothing special given, then go for SN1.
