Abstract: In order to facilitate learning nucleophilic substitution and elimination, 17 comprehensive introductory organic chemistry textbooks are compared . Elimination reactions typically form after the wholesale removal of a substituent, with no replacement. This means it is both a good nucleophile and a strong base. The study of structure determines their chemical composition and formula and the study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. For example, whatever you do with tertiary halogenoalkanes, you will tend to get mainly the elimination reaction, whereas with primary ones you will tend to get mainly substitution.
