H₂C CH3 Br CH 3

2) Draw all products formed in the following SN1 reaction. Br CH;CH2OH

Choose which compound is more reactive when reacted with N2OH in water solvent and he reason clearly. vs OH HO,

HOW MANY DIFFERENT ENOLS COULD BEFORMED FROM the structuRE BELOW ? &

please help with all parts

For each of the following reaction, fill in the missing starting materials ,reaction conditions, or products. If more than one product is formed, draw only the major organic product. If no reaction occurs, write “no reaction.” Indicate appropriate stereochemistry only when necessary. If multiple steps are required, use numbers to indicate order

(a) Draw the product of the following [4 + 2] cycloaddition, which was carried out in the early stages of the synthesis of the alkaloid reserpine (Problem 22.83). Indicate the stereochemistry at any newly formed stereogenic centers. (b) Draw the p orbitals of the alkene and the terminal carbons of the conjugated diene, and show how the orientation of the reactants and orbital overlap lead to the observed stereochemistry.

a) How many different molecules containing one double bond can be used to synthesize 4-methyl-4-heptanol (as the major product) via acid catalyzed hydration with H2SO4 and H2O? Draw them all below. b) Are any of the structures in part (a) trisubstituted alkenes? If so, redraw it/them below.

conjugated ring with alcohol reacts with I2, NaHCO3 with CH2Cl2 and H2O. What will be the product?

Draw the structure of a compound of molecular formula C6H10 that reacts with H2 in the presence of Pd-C but does not react with H2 in the presence of Lindlar catalyst.
