K2Cr2O7 / H2SO4; reflux; see yellow 6.1.2 flashcard 1. 1 of 8 Explain the nucleophilic addition reaction of carbonyl compounds to form alcohols. NaBH4 / H2O; see yellow 6.1.2 flashcard 2. 2 of 8 Explain the nucleophilic addition reaction of carbonyl compounds to form hydroxynitriles. HCN, H2SO4 / NaCN; see yellow 6.1.2 flashcard 3. 3 of 8 What is the mechanism for the reaction carbonyl compounds with NaBH4? Nucleophilic addition; see yellow 6.1.2 flashcard 4. 4 of 8 What is the mechanism for the reaction carbonyl compounds with HCN? See yellow 6.1.2 flashcard 5. 5 of 8 How can 2,4-DNP be used to detect carbonyl compounds? In the presence of a carbonyl group, a yellow or orange precipitate is produced. 6 of 8 What can Tollens' reagent be used to identify? Tollens' reagent is a solution of silver nitrate in aqueous ammonia; in the presence of an aldehyde group, a silver mirror is produced. 7 of 8 How does Tollens' reagent work? Tollens' reagent contains silver (I) ions, which act as an oxidising agent in the presence of ammonia; see yellow 6.1.2 flashcard 6. 8 of 8
