Compound 1 and 4 will undergo racemisation. Explanation: The racemisation is defined as mixture of different optical isomers in a reaction. Racemisation can only occur if the compound has chiral carbon. In case of 1st compound, it's 2 bromo propane. It has a chiral carbon with four groups being hydrogen, ethyl, bromo and methyl groups on four bonds. So with treatment with aqueous KOH, the compound will form 2 propanol. Similarly the last compound is 2 chloro butane, the chlorine group will be substituted with hydroxyl group. So both of them will undergo racemisation as the mechanism is SN1.
