(a) benzoic acid itself in water is insoluble due to the hydrophobic benzene ring which
disrupt the H-bonds between water-water and water-benzoic acid. It is more soluble I
ether as it shares same properties with ether in molecular terms. CCl4 is non-polar
solvent however benzoic acid is not non-polar therefore its not soluble in CCl4. so the
right answer is benzoic acid is most soluble in ether.
(b) Sodium benzoate is sodium salt of benzoic acid which can dissociate into two ions
Na+ and benzoate ions. Since it is an ionic solid, therefore, it is soluble in water since
due to polar properties of water, all polar and ionic solids dissolve in water.
(c) 1. Ether has lower density than water which means that top layer will be eth
