Because alcohola are much less acidic than carboxylic acid or minral acids, they don't react with weak bases such asamines or bicarbonate ion, and they react to only a limited extent with metal hydroxides such as NaOH. Alcohols do, however, react with alkali metals and with strong bases such as sodium hydride (NaH), sodium amide (NaNH2), and Grignard reagents in organic chemistry.
