When acyl halides (R?COX) or acid anhydrides (R?OC?O?CO?R) react
with primary amines (R?NH2) or secondary amines (R2NH), the
reaction yields an amide:
O || R?C?NR2
where R may be an alkyl group or hydrogen atom.
For example, propanoyl chloride
( O ||CH3CH2C?Cl)
reacts with ethanamine (CH3CH2NH2) to form
(O || CH3CH2C?NHCH2CH3).
The IUPAC name for the product isN-ethyl propanamide, as
it is formed from ethanamine and propanoyl
chloride.

Epoxides, like bromonium ions and mercuronium ions, can be
ring-opened with various nucleophiles. The stereochemistry of the
product depends on if the ring-opening occurs under acidic or basic
conditions. The following two reactions – ring opening of an
epoxide with water – illustrate this effect. Explain why the
outcome of the reaction changes under these two conditions and
provide electron-pushing arrows to explain the mechanisms.
