Question

Add curved arrows to the reactant side of the following SN2 reaction. Given the following single-step reaction, draw the curved-arrow mechanism. Add two curved arrows to the reactant side to illustrate the movement of electrons in the E2 reaction below. (There will be a total of three curved arrows, one of which is drawn for you.)

Answer 1

он CH30 H3 CO CH2CH3 СНЗ СНЗ СНЗ он он The primary alkyl halides in presence of strong base are driven the reaction into SN2 reaction. But tertiary alkyl halides have two possibilities while reacting with base concentration. Bulky base like tertiary butoxide driven the reaction as eliminated product, where the strong and less hindered base driven the reaction as substituted on tertiary carbo cation as SN1 reaction.
