Answer:
. Ammonium chloride suppresses the ionisation of NH4OH and (NH4)2 CO3 due to common ion effect which results in the decrease in the concentration of OH– and CO32- ions. So the ionic product does not exceed the solubility product of Mg(OH)2 or MgCO3 and thereby they are not precipitated in V group.
