NaBH4 2. LiAlH4 sodium borohydride - Correct Answer 1. only reduces aldehydes and ketones 2. NaBH4/ H2O, methanol, or ethanol lithium aluminum hydride - Correct Answer 1. reduces everything 2. very flammable and can't be around water 3. (1) LiAlH4, Et2O / (2) H2O aldehydes vs. carboxylic acids - Correct Answer Aldehydes are easier to reduce because they only have two resonance structures, whereas carboxylic acids have three. This gives the aldehyde carbonyl a partial positive charge at least 50% of the time. the carboxylic acid carbonyl only has a partial positive charge 33% of the time.
