Concept explainers
a)
Interpretation:
The formation of given compound from 3-methyl-1-butyne has to be shown.
Concept introduction:
Addition reaction:
Markovnikov’s rule:
In the overall addition reaction, the hydrogen atom (electrophile) is bonded to least substituted carbon and nucleophile is bonded to the most substituted carbon. This is known as Markovnikov’s rule.
b)
Interpretation:
The formation of given compound from 3-methyl-1-butyne has to be shown.
Concept introduction:
Addition reaction: Alkene reacts with polar reagent (HBr, HCl) across the double bond, leads to the product of alkyl halide.
Addition of bromine across the double bond in the presence of Lewis catalyst undergoes addition reaction leads to formation of products.
Markovnikov’s rule:
In the overall reaction, the hydrogen atom (electrophile) is bonded to least substituted carbon and nucleophile is bonded to the most substituted carbon. This is known as Markovnikov’s rule.
c)
Interpretation:
The formation of given compound from 3-methyl-1-butyne has to be shown.
Concept introduction:
Addition reaction: Alkene reacts with polar reagent (HBr, HCl) across the double bond, leads to the product of alkyl halide (Or)
Hydrogenation of alkene: Addition of hydrogen molecule across the double bond in presence of catalyst undergoes hydrogenation of alkene.
Markovnikov’s rule:
In the overall reaction, the hydrogen atom (electrophile) is bonded to least substituted carbon and nucleophile is bonded to the most substituted carbon. This is known as Markovnikov’s rule.

- Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)arrow_forwardHi I need help on the question provided in the image.arrow_forwardDraw a reasonable mechanism for the following reaction:arrow_forward
- Draw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
