Predict the compound in the following pair that will undergoes solvolysis (in aqueous ethanol) more rapidly.

It is the reaction in which water molecules donates its lone pair of electrons to the antibonding molecular orbital of the group. It is a neucleophilic substitution in which the leaving group is replaced by -OH group in the final stage.

Explanation:

Solvoylsis is the ionization of the molecule made by the solvent in this case the solvent is ethanol( CHCH2OH).  Hence, in this all the compound from a to f form the most stable cation.

The compound (CH3)3C-CL undergo solcolysis rapidly because it will form tertiary carbocation. Chlorobutane undergo solvolysis directly. Then bromocyclohexane undergo solvolysis rapidly since it forms secondary reaction.
