Question

In each reaction box, place the best reagent and conditions from the list below. CrO_3, H_2SO_4 KMnO_4 H_2O_2 CH_3CH_2Br H_2O NaBH_4 NH(CH_2CH_3)_2, H_3O^+ (cat.) CH_3CHO, H_3O^+ (cat.) NH_2CH_2CH_3. H_3O^+ (cat.) CH_3OH. H_3O^+ (cat.) NH_2CH_2CH_2CH_3, H_3O^+ (cat.) PCC H_3O^+. H_2O, heat LiAIH_4

Answer 1

1) CH3OH, H3O+ (cat.)

2) LiAlH4

3) H2O

4) PCC

5) NH2CH2CH3, H3O+ (cat.)

Explanation: Reaction of amide with alcohol in presence of acid catalyst produces ester as product. Reduction of ester with LiAlH4 produces alcohol as product. oxidation of alcohol with PCC produces aldehyde as product. reaction of aldehyde with primary amine produces imine as product.
