Answer to Question #249528 in Organic Chemistry for Trac

Question

3. Adding HCl to the above amines make them all soluble in water. Write the equations for the addition of HCl to the amines, and describe why the addition of HCl makes them all soluble in water

a. 1-butanamine

b. N-methyl-1-butanamine

c. N,N-dimethylbutanamine

d. Why do these reactions increase their solubility?

Answer 1

a) C4H12ClN

b) C5H13N

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
