Discuss what you would observe after elution and visualization of a TLC plate having made the following mistakes in carrying out the analysis. Conceptual Organic chemistry
Many drugs are high-molecular-weight amines that are weak bases. Such amines are not soluble in water, which limits the ways they can be administered and means that they are not soluble in body fluids such as blood plasma and cerebrospinal fluid
The entropy of a gas is larger than that of the liquid because the specific volume of gas is greater thus implying more mutual configurations are allowed for molecules in a gas than in the corresponding liquid.
