How would you describe the reaction between NaOH (a base) and the mixture of
benzoic acid and methyl benzoate?
Both react with NaOH because bases accept protons
Neither react with NaOH because neither has an acidic proton
Benzoic acid reacts with NaOH because it has an acidic proton, but
methylbenzoate does not

Primary amines can be prepared from nitriles by reduction with LiAlH4. The two-step sequence involves SN2 displacement of halide ion by cyanide ion followed by reduction, and yields a primary amine
with one more carbon than was present in the alkyl halide.

Amines (R-NH2, R₂NH, or R³N) are the organic analogs of ammonia (NH3) where one or more of the hydrogens on the nitrogen has been replaced by an alkyl group (R). Like ammonia, amines are basic with pKb's in the same range as the pka's of carboxylic acids. Amines readily form their water soluble conjugate acids in the presence of 5% aqueous HC1.
