Show the full mechanism
Which intermediate is involved in the reaction shown? Formation and reactions of carbenes with alkenes. The reaction conditions are rather specific for this reaction and probably must be taken into account. The potassium tert-butoxide is a sterically hindered strong base. When trihalomethanes are treated with the strong base, deprotonation gives the trihalomethyl anion, which loses a halide ion to give the neutral carbene. The dihalocarbene adds to the alkene in a a cycloaddition reaction to give...

Regioselectivity of E1 and E2 Reactions 3. The reaction between a 1,2-dimethylcyclohexanol and concentrated strong acid results in an E1 reaction. Show the first step in this reaction (consider that the acid catalyst can protonate the OH group which eventually can form H2O that can act as a good leaving group). а. сн, OH conc.H2SO4 CH3 b. What is the geometry at the reaction center of the intermediate? Show the final step and all possible alkene products с. State the...

Carboxylic acid esters can undergo acid catalyzed hydrolysis, neutral hydrolysis and base catalyzed hydrolysis. Below is a table with three structurally related carboxylic acid esters and the second order reaction rate constants for the acid-catalyzed mechanism (k_A) and the rate constant for the base-catalyzed mechanism (k_B). The difference between the three compounds is mainly the substitution of hydrogen atoms on R_1 with the more electronegative chlorine atoms. a) Explain why there is only a small change in k_A for the...

g. Draw the Snl mechanism of the reaction between 2,5-dimethyl-2,5-hexanediol and hydrochloric acid (excess). Show lone pairs, electron pushing arrows, 3-D view to reflect appropriate stereochemistry, reactants, intermediates, and products. You do not have to show transition states. Name the product. Draw and completely label a reaction energy diagram corresponding to the mechanism you have drawn.

A. One mechanism of fragmentation is loss of a neutral radical by cleavage of a bond from which one electron has been lost. What is the m/z ratio of the most stable cationic fragment that can be generated from dexchlorpheniramine by this mechanism? Show the structure of the fragment and discuss charge stabilization. B. The base peak in the dexchlorpheniramine mass spectrum occurs at m/z 203. A peak with relative intensity 33.1 occurs at m/z 205. Interpret this information with...
