Question 2 (1 point) Reaction conditions for the use of NaBH4 and LiAlH4 as reducing agents are different. LiAlH4 is the more difficult to handle. Explain why it reacts violently with water can't be used in the open air needs special anhydrous solvent all the above Question 1 (1 point) What class of compound do you always get if you reduce an aldehyde? O 2º alcohol carboxylic acid ketone 1° alcohol

using the procedures, we used dichloromethane as the unknown
mixture and i was able to extract benzoic acid for an acid,
5-chloro-2-methoxyanaline for a base compound and biphenyl for
neutral compound.
i don't know if that answers the missing part but if it didn't
could you be specific please? thank you!
