help wich options are correcet a,b ,c ,d ? thanks
A physical property you will examine is miscibility, or whether one chemical species will mix with another. "Like dissolves like" is no longer enough to describe interactions between molecules, as more complex molecules require a more detailed approach. You will use interactions between species to explain miscibility in both a polar (water) and non-polar (hexane) solvent. The key is to compare the strength of interactions in the pure sample versus the mixture of chemical species. Select which of the following statements regarding miscibility is correct. Experiment shows that CH_3 (CH_2)_4 CHO is basically immiscible in water! This experimental result may not have been predicted as they are both polar species. NaCL is insoluble in hexane; this means that the ionic forces in NaCL must be stronger than the ion-induced dipole forces that can occur between NaCL and CH_3 (CH_2)_4 CH_3. If chemical species are miscible in one another, the interactions between them cannot be weak forces like London dispersion forces. If chemical species are miscible in one another, the interactions between the two species must be weaker than those in the pure samples.
