Question 1 a) Consider the scheme below to answer questions (i) to (iii) 1. LDA 2. CH.CH.CH -78C A B (i) Which product is likely to form under the conditions given on the scheme above? (2) Explain how you arrived at your answer above. (2) Provide suitable conditions to obtain the product not formed under the given conditions. Do not provide mechanism (2) b) Provide suitable conditions, C, required to complete the reaction given below. No mechanism required (5) c) Give the structures of the two products (D and E) expected to form when treating 3-methylbutanal with NaOet at room temperature for 18 hours, as shown in the scheme below. No mechanism required NaOEV 1,18 hrs a) Complete the following reaction scheme by providing the missing reagents and product A-E. No mechanism is required (10 marks) i) NaOET ii) Br B. CH3 a) HB i) Mg H/HO OH + HPO4 Heat D b) While trying to synthesise the product F following the reaction scheme shown below, the desired product was never obtained. Instead an unwanted product G was obtained in 100% yield. Provide the detailed mechanism of how this product formed and suggest a new synthesis, starting from the given starting material to obtain product F. No detailed mechanism required (10 marks) 1.
