Organic chemistry mechanisms i need help with systheses questions 6,7,8,9 2-hydroxybenzoic (3 pts) 5. Provide an appropriate structure for: 3,3-dimethylcyclobutanecarbonitrile. (4 pts each, unless otherwise noted, 12 pts total) 6-8. Syntheses: draw / provide the likely organic product(s) generated in each of the reactions (or reaction sequences) below. As appropriate, pay attention to regiospecificity (new bond formation and location in the product formed) and stereochemistry (direction in space of new bond(s) formed). Indicate ALL likely products: where one product does...
1. 3-methyl-1-butene on reaction with H-Cl forms two products, namely 2-chloro-3- methylbutane (minor) and 2-chloro-2-methylbutane (major). Illustrate the mechanism for the formation of these two products. Use curved arrows to illustrate electron movement and all intermediates must be shown. 2. 3,3-dimethyl-1-butene on reaction with HBr forms two products, namely 3-bromo-2,2- dimethylbutane (minor) and 2-bromo-2,3-dimethylbutane (major). Illustrate the mechanism for the formation of these two products. Use curved arrows to illustrate electron movement and all intermediates must be shown. 3. Calculate...
help Thank you 4. (10 pts) Draw all possible products for the following reaction including stereoisomers. Note that the addition occurs through a "syn" mechanism. Is the product solution optically active (yes or no)? 1. BAHATHF 2. NaOH, HO (8 pts) Provide a complete mechanism for the reaction below and include lone-pairs of electrons and formal charges. Show all products formed including stereoisomers. Is the product solution optically active (yes or no)? Bras 11. (8 pts) Draw all four regiochemical...
