Persistence. KB. A discussion of acid-base terminology is available here. Which statement below is true? Solvent was evaporated and methylene chloride was added . Industrial synthesis of dimethylacetamide.svg. It is a strong organic base, and since it is stronger than the inorganic hydroxide ion, it can remove a hydrogen atom from a water molecule, yielding methanol and hydroxide. These are extremely weak and cannot be analyzed using normal titrimetric methods. Typically, organic chemists compare the various values from their determination in water, DMSO and the gas phase and use these to predict a compounds reactivity, solubility, and other physical characteristics.
