please help me with Organic Chemistry/Alkenes problems. Thank you! Directions: Place your answers to the following questions in the spaces provided. 1. A common problem in the acid-catalyzed hydration of alkenes is the formation of an ether byproduct. Show the formation of the ether byproduct in relation to the reaction below by providing a curved-arrow mechanism for its formation. (2 pts) H30+ Н,0 OH Ans. 2. Which is the correct sequence of steps necessary to complete the following reaction? он...
Complete the following reactions. Provide the missing reactant(s) OR major organic product(s). Show correct regio- and stereochemistry for products you draw, where applicable Сн,, Zn(Cu) 1. OSONMO, pyridine 2. NaHSO, H,0 H2O* g. V 1. BH-THF 2. 1,0,, NaOH, HO - Y 1. MCPBA 2.4,00 DCM H,802, H2O heat 1., 2. Zn, AcOH
this is organic chemistry, please help with both if you can. 1. Give the missing reagents, reactants or products for each of the following reactions. Answer the question associated with part b; if stereochemistry is required, you need to show dashes and wedges on the chiral centers only. (3 pts) a. Hyllindlar H2O/H HI b. give one stereoisomer OH HB/ROOR How many possible stereoisomers are produced? E1 give one stereoisomer PCC Excess H, H CHC12 d. OH KMnO4 HO H...
Predict the products the alkenes shown below would produce on exposure to each of the reagents (i)-(iv) (4 reactions X 5 alkenes = 20 products). Pay attention to both regiochemistry and stereochemistry (syn or anti addition). You may draw just one enantiomer of any chiral product, though both enantiomers will be produced in equal amounts. (i) BH3, then NaOH, H2O2 (ii) Hg(OAc)2 in H2O, then NaBH, (iii) Bra in CH3CH2OH Autumn 2019 EM 223 (iv) Cl2 QUÝ" H H
