What is the reagent used? Reduction- Nucleophilic addition. NaBH4. 1 of 18 How to turn a carbonyl into a hydroxynitrile? What reagent is required? Nucleophillic addition. KCN/HCN. 2 of 18 What is the product of acyl chlorides with water? Carboxylic acid. 3 of 18 What is the product of acyl chloride with ammonia? Amides. 4 of 18 What is the product of acyl chlorides with alcohol? Ester. 5 of 18 What is the product of acyl chlorides with primary amines? N-substituted amines. 6 of 18 What is the reaction mechanism for acylation using acyl chlorides or acid anhydrides? Addition-elimination. 7 of 18 How to make primary amine from haloalkane? What conditions and reagent? Nucleophilic substitution. Excess NH3. 8 of 18 What reagent is required for the reduction of nitrile to form a primary amine? LiAlH4 in Ether. 9 of 18 What is made from a dicarboxylic acid and a diol? Polyester. 10 of 18 What is made from a dicarboxylic acid and and a diacyl chloride? Polyester. 11 of 18 What is the reaction to turn benzene into nitrobenzene? Electrophillic Substitution. 12 of 18 How to turn nitrobenzene into phenylamine? Reduction using Sn in conc HCl. 13 of 18 Why is phenylamine a weaker base than ethylamine? Lone pair less available as it is delocalised into the ring. 14 of 18 Reagents needed to make nitrobenzene? How to form the elctrophile NO2+? Concentrated HNO3 and Concentrated H2SO4. HNO3+H2SO4 -> NO2+ + H2O + HSO4. 15 of 18 What reducing agent is used in the reduction of aldehydes and ketones? NaBH4 (H-) 16 of 18 Why can Polyesters and polyamides be broken down by hydrolysis? They contain polar bonds which attract attacking species(nucleophiles) 17 of 18 How to form the electrophile AlCl4-? AlCl3 + CH3COCl -> CH3CO+ + AlCl4- 18 of 18
