Amines, reactions Amines are similar to ammonia in their reactions.

Amines, reactions Amines are similar to ammonia in their reactions. Like ammonia, amines are basic . Like ammonia, amines are nucleophilic and react with alkyl halides, acid chlorides, and carbonyl compounds. The aromatic amines are highly reactive in electrophilic aromatic substitution.

Conjugate Pairs

Conjugate Pairs. The strength of an acid (or base) is determined by the amount of IONIZATION . HNO 3 , HCl, H 2 SO 4 and HClO 4 are among the only known strong acids. Strong vs. Weak Acids. Strong acid is one that ionizes completely
