    answer is b). Water being a polar solvent, dissociates like this: H20--->H+ + H0- (in equilibrium) Polar compounds too(like NaCl) dissociate: Na+Cl---> Na+ Cl- so the style likages like Na--H and HO----Cl. different water molecules style hydronium ion: H20 + H+ + HO- -----> H30+ + HO- Hydronium ion So the too dissolve. Molecular solids and crystalline solids in wonderful condition into the gaps or intermolecular areas b/w the water molecules this is the non polar hydrocarbons that can not dissolve in water, yet can in organic and organic solvents like benzene, Carbon disulphide etc. it quite is by using the shown fact that non ploar hdrocarbons do no longer dissociate. Neither can the link to the H+ and HO- produced by using water.
