Which of the following reaction steps proceed during the El elimination reaction below? (Steps are not necessarily in the same order as that of the overall reaction mechanism). Base Cl Nucleophilic Attack Loss of a Leaving Proton Transfer Hydride Shift Methyl Shift IV ,vD.IL. I.IVE. IL,II,V 1, II I, II, IV 2. Which of the following functional groups can react with a primary amine? (Your Nucleophile/Electrophile Guide be helpful here!) an organomagnesium reagent B. an enolate (C.a primary alcohol D. an aldehyde E. an ether 3. Which of the following bases would lead to the largest relative amount of Zaitsev elimination (more-highly substituted) product when it reacts with 2-chloro-2-methylpentane? CI 4, which of the following alkenes is expected to have the highest reaction rate when its C-c pi bond reacts? R H H R H R S. Which of the following variables significantly affects the regiochemistry of an E2 elimination reaction? A Strength of base (pKaBH) B Amount of base used C Temperature ofreaction E. All of these significantly affect the regiochemistry of an elimination reaction D Siebík ness ofbase

Explanation / Answer

Ans 1. during E1 since it is first order so first leaving group leave system then formation of carbocation take place then further hydride shift to stablise carbocation since 3 degree carbocation are mosre stable then proton abstration takes place using and strong base.so option D.

Ans 2. option C

ans 3. base should be strong and small since generally E1 mechanism so NaOH is best.

Ans 4. it will show reation through addition mechanism so less bulkier the c=c more reaction rate so optiom D is best.

Ans 5. mostly the bulkiness of base will decide since base will decide from where the proton have to be abstracted.
